Fantastic experience: Absolutely love TEF. I was lucky enough to meet Ken, the owner, while he was working on opening and I joined as soon as my work schedule would let me earlier this year! The 6AM crew keeps it real, they DFQ.

Jennifer C 2 years ago

Fantastic experience: I highly recommend The Endurance Factory! Supportive coaches, inclusive environment, any fitness level is welcomed! My fitness has improved so much in the last year from going to TEF and I've learned so many new skills. I'm so glad I found TEF! I can go on and on......

Fantastic experience: The gym is nice and clean, many people use it, and the staff is friendly. I go there whenever I can because it is close to my house.

Alexander Gray 2 years ago

Fantastic experience: Excellent CrossFit, powerlifting, and Olympic lifting facility. Several bars, platforms, plates, collars, and racks. The gym was also spotless. We didn't see anyone when we went on Sunday morning, so it's unclear how crowded it gets during peak hours.

Adam Katz 3 years ago

Fantastic experience: It's a very welcoming space with a great atmosphere. The staff is always eager to help and they have all the latest equipment, which they often keep up to date. The Endurance Factory Fitness is the best CrossFit Gym. I've been going there for 2 years now and my endurance has improved significantly.

Fantastic experience: This place is exactly what I wanted; no pressure, no upsells. It's a local gym, and I generally don't have a problem getting to the equipment I want to use. The attendants are nice and professional. They have a nice selection of trainers that you can work with. The equipment is good. My friend recommended a nice place for me.

Fantastic experience: I love this The Endurance Factory Fitness! The staff is so friendly and helpful. They have a great range of equipment from treadmills to free weights, and plenty of space in the exercise area. There are also lots of classes to choose from, it's my favorite place to go.

Harley Smail 3 years ago

Fantastic experience: It is an amazing gym. It has everything you need for strength training/bodybuilding/conditioning. It is available, and the monthly membership is very reasonable. The owner of The Endurance Factory Fitness is friendly and welcoming, and you'll quickly feel at ease here. One of the best gym for anyone serious about training/conditioning, I will recommend.

Fantastic experience: Wow , I went online and signed up for the 7 day trial for $7, signed up for a class that same day through their easy to use app. Got off work and was in the 5PM class hosted by Sara, we had music, motivation and sweaty bodies . I’ll admit I struggled as a first attempt rookie, but with the help of a classmate and Sara I still got a great workout. It is amazing to finally find a gym with no judgment and lots of support for individual needs, I felt like I was a part of a team. Highly recommend this gym and classes to anyone seeking self improvement. Time to fuel up rest and be back tomorrow for another class, looking forward to seeing you all.

Brenda Smith 3 years ago

Fantastic experience: Awesome gym! Has more than everything I need. Great to try new things. Very clean which is a necessity for me. 24/7 is super clutch. Staff is very welcoming. Convenient location. I recommend this place to anybody.

Adam Wood 3 years ago

Fantastic experience: The Endurance Factory is an OCR/Ninja Warrior style gym that offers personal training and boot camp classes! The owner, Ken, has participated in numerous Tough Mudders, Spartan Races, Terrain Races, Warrior Dash, Savage Race, OCR World championships, etc. He lends that knowledge and expertise to all gym members! All of the other trainers are knowledgeable and friendly. TEF offers several forms of classes: Crossfit/Workout Of The Day (Strength training followed by HIIT), Obstacle Fit (high intensity and geared towards OCR prep), and IntervalFit (bodyweight and cardio). The gym became a Crossfit affiliate and holds several DEKA events per year. The trainers and the members make the gym what it is. I've been going to classes with the same core group of people since it opened. If you are looking for a great workout with a fun and friendly atmosphere, The Endurance Factory is the gym for you!

Lindsay Wooten 3 years ago

Fantastic experience: WORTH CROSSING STATE LINES FOR. I first came to TEF for a class through the recommendation of a friend. It’s a bit of a drive for me (over an hour) but the coaches and classes are worth it. When I wanted to start running Spartan races competitively, I knew this drive was going to make a huge difference in my racing. And it did. I went from being a middle-of-the-pack runner to securing a few podiums. So when TEF introduced its Comp Team program, again, I knew it was something that I wanted to be part of. Through the program, I was able to identify areas I really needed to work on, sharpen my racing skills, and uncover some strengths I didn’t know I had. It was amazing to work with other athletes who are constantly pushing you to be and do better, who support you, even when they’re competing with or against you. If you are ready to level-up, TEF is an amazing place to do so.

Samantha DiPietro 3 years ago

Fantastic experience: Hands down the best gym I've ever been to! I'm am more of a work out a home type of gal but my husband encouraged me to do a free trial and I have been going ever since. The apps they incorporate are awesome to track your weights/reps/time to see your progression over time. Many times attending public gyms I felt like I had to keep up with the person next to me or didn't feel confident that I was doing the workouts correctly. At The Endurance Factory I am able to get in my zone and my only competition is myself! I love that the coaches are there to assist, encourage, and modify the workouts to everyone's individual ability levels and there's no absolutely pressure or judgements. Beware: joining this gym may have side effects such as an increase in self confidence, elevated mood levels, and strength you never knew you had!

James Caroland 3 years ago

Fantastic experience: I turn 50 next year, and have been an athlete and worked out most of my adult life, yet I'm in the best shape of my life thanks to The Endurance Factory (TEF). I'm much more functionally fit now and have become more competitive in my favorite activity of Obstacle Course Racing, even taking 2nd place at a recent race. The coaches are great. They understand your goals and needs and will help tailor workouts to meet them. Beyond fitness, I consider TEF coaches and athletes my second family who are supportive of me in all aspects of my life. Whatever your fitness goals are, if you want to be a better human, you should join the TEF family.

Kathryn Willman 3 years ago

Fantastic experience: Positive: Communication , Professionalism , Quality TEF has become family in the short 2 months we've been here. Welcoming, friendly, caring, hilarious, hard workers. The programming is focused, working smarter not just harder. Ken, Cheryl, and all the coaches care about each of the athletes, not showing favoritism. Members are real people who also hangout outside the gym.

Mark O. 4 years ago

Fantastic experience: The location isn't exactly convenient for me. It takes me 40 minutes to get there but it is well worth it. I probably passed a dozen other gyms to get there but the staff and the other members make it well worth the trip. I haven't found any other gyms within an hour of my home that are quite like this one. It was exactly what I was looking for.

Fantastic experience: Positive: Professionalism , Quality The Endurance Factory provides a great community and fantastic workouts. Not having to plan exercises or build a schedule makes the motivation that much easier, just show up.

Saikrishna Bhavaraju 4 years ago

Fantastic experience: This is hand down the best gym I've ever been. Love the way the coaches encourage you to push harder and pay attention to your form. The friendly environment from not only the trainers, but also the people working out right next to you, is so comforting and encouraging. You are not just another person walking in. After working out with The Endurance Factory I have realized why people say that working out or exercising is addicting. If you are serious about what you want, if you work hard consistently then this place is all you need to become a better person than you already are.

Tessa Goldscher 4 years ago

Fantastic experience: Positive: Communication , Professionalism , Quality The Endurance Factory has been a game changer in my workouts. I am challenged both physically and mentally. The coaches are encouraging and truly care about the members. TEF has made me enjoy working out! My gym family is amazing and supportive. You won’t find this anywhere else.

Jackie Spicer 4 years ago

Fantastic experience: The Endurance Factory is the first gym that has convinced me that working out isn’t something I HAVE to to but something I actually want to do. The workouts are fun, engaging, and challenging but can be scaled up or down depending on your skills and confidence levels. Above all, the community of athletes that workout with me is why I keep coming back!

Amanda Cohoon 4 years ago

Fantastic experience: Positive: Communication , Professionalism , Quality I can’t express how glad I am that I found The Endurance Factory. The dedication to their members and the support from not only the coaches but everyone that steps foot in the building is beyond incredible! If you’re looking for a gym in the Savage area, you won’t find anything better.

Peggy Roybal 4 years ago

Fantastic experience: I love The Endurance Factory!! The coaches are always so warm and welcoming. Anytime I come to the workouts the coaches are very helpful with my form and they are encouraging. I love that the other members are inspirational and push me to finish my workout strong. I definitely recommend The Endurance Factory to anyone who is looking for a change of pace in their workout routine and fitness journey and want to be part of a family.

Andrew Smierciak 4 years ago

Fantastic experience: Positive: Communication , Professionalism , Quality Absolutely amazing gym. Feels more like a family who gets fit together than your standard workout. I’ve seen more personal progress in two months at the endurance Factory than a year taking myself to the gym. Highly recommend you try it out if you’re looking for a place to get fit, make friends, and have fun.

Heather Schultz 4 years ago

Fantastic experience: I'm so glad I joined TEF almost a year ago! I love that the workouts vary and that any workout can be modified for your current level. More importantly, the support and encouragement from the coaches is amazing. The energy in the gym is inspiring and contagious.

Jonathan Lee 4 years ago

Fantastic experience: Positive: Communication , Professionalism , Quality Hands down the best fitness experience I’ve ever had the pleasure and honor in being a part of. It’s not just the professional, knowledgeable, and friendly staff; it’s also the amazing community that they’ve built. Looking forward to TEF being my one stop shop lifelong fitness.

Jessica Kaplan 4 years ago

Fantastic experience: Positive: Communication , Professionalism Absolutely love The Endurance Factory! Each workout is different and designed to challenge us every day. There are people of all fitness levels and have such a welcoming/family vibe! Can’t speak highly enough of this gym. It’s like my home away from home

Cassondra Lyko 4 years ago

K.J. H. 4 years ago

Fantastic experience: The Endurance Factory is nothing short of a magnificent, transformative experience. As a member, on and off, for a handful of years I’ve come to know it to be a diverse community that treasures health and wellness. My initial goal was to find a facility that didn’t force me to suffer through mundane workouts – an hour on the treadmill, a run around the track. I was looking for an experience that kept me engaged and really pushed me. I found it in The Endurance Factory. The body-weight workouts, the unpredictability of these workouts keeps me on my toes and makes me want to come back for more each and every day. There is a balance of beginners (like me) to elite athletes, but unlike other facilities, my interaction with fellow members is never intimidating and always inspiring. The Endurance Factory experience lends itself to that camaraderie amongst members. I can’t speak highly enough of the truly superior, stellar coaching staff. Slowly but surely I’m becoming strong and healthier well beyond what I could have fathomed. I have developed both strength of heart, mind, and body because The Endurance Factory has taught me just that… how to endure and overcome what once felt insurmountable.

Frederick Whittington 4 years ago

Fantastic experience: The endurance factory is a wonderful gym with a focus around training for obstacle course races. It definitely is a huge help in conditions for any level of race. The group of people that take the class range from people who are just trying to start at getting back into shape to avid racers. Ken and everyone always make everyone feel welcome.

Jenny I. 4 years ago

Fantastic experience: Update: I have now been at The Endurance Factory for about 2 and a half years and I am still so happy that I made the decision to join this gym. Over the past few years, I have been able to achieve goals that I never thought I would achieve. I believe a lot of this is due to Coach Ken’s consistent care, knowledge, and belief in every member of this gym. He sees our strengths and our mental roadblocks and he will never quit on you no matter what. This kind of authentic care and consistent character has helped me push myself forward into becoming a stronger version of myself. Coach Ken, thank you for believing in me and never giving up on me. When I look back at the beginning of this journey, I just can’t believe how much I have progressed. You not giving up on me has helped me move forward. If you are looking for a gym that focuses on functional fitness through group classes with caring coaches and within a strong and encouraging community, this is the gym for you. —————————————— Joining The Endurance Factory (TEF) was one of the best decisions I ever made. A few months ago, I tried out several gyms in the area in hopes that I would find the perfect facility. I was looking for a gym that would not only challenge me mentally and physically but also align with my values. My hope was also to become a little beast. After trying out several gyms, I came across TEF. I had wanted to challenge myself for a few years with Obstacle Course Racing and was so excited to come across this amazing gym. I contacted Coach Ken, the owner, and signed up for a free class. Coach Ken welcomed me on my first day, showed me around the facility, had a genuine interest in my goals, and helped me get through my first workout which was exactly what I was hoping for - physically tough with a healthy dose of mental toughness. I am now a few months in and I am so happy that I made the decision to join. So, why join The Endurance Factory? What sets them apart? 1. You will be working with AMAZING coaches who genuinely care about you and your progress. Coach Ken and Coach Tiffany are kind and intelligent and will motivate you to move forward towards your goals even on those days where you feel like you can't. They are positive, empowering, and authentic. You can tell that helping others reach their goals and overcome their obstacles (physically, emotionally, and mentally) are truly their passion. 2. The community is awesome and supportive. You will be working side by side with people who celebrate your successes and encourage you through your areas of opportunity. The environment is positive, encouraging, and just a happy and fun place to be! 3. The workouts are TOUGH but worth it. You will see results! Just DFQ! 4. TEF is affordable and you definitely get way more than you pay for and there is no sales pressure whatsoever. 5. You will get ripped. Keep up the great work team TEF! You're making a difference. -Jenny I.

Fantastic experience: Positive: Communication , Professionalism , Quality I love coming here! All the coaches are great and go out of their way to make you feel welcome. The workouts are challenging you every day and they never disappoint! Highly recommend this place for all your fitness goals/needs.

Josh Wolf 4 years ago

Fantastic experience: I wanted to progress as a competitive athlete but it was hard for me to check all the boxes each week and know for sure if I was on the right track. Ken’s programming has completely turned my training around and has taken out all the guess work. I now have a fine tuned plan of attack. We attack my weaknesses, both mental and physical, and we are hitting all facets of training that competitive endurance racing requires. Ken is constantly analyzing the data from sessions and tracking progress, as well as, monitoring fatigue and warning signs for overtraining or potential injuries. Ken is completely dedicated to helping me achieve my athletic goals and it shows in every detail in his preparation, attentiveness and drive.

Tambri Cason 4 years ago

Fantastic experience: The coaches and owner here are amazing! They bring an element to the Endurance Factory that I’ve rarely experienced at other gyms.. they’re invested in the success of ever single member in their class! From fitness to nutrition, they’ve figured out what works and do a fantastic job of sharing that knowledge and passion with others! This gym is top notch if you’re looking for a fun, competitive, family-like atmosphere!

Jennifer G 5 years ago

Fantastic experience: I joined TEF in December 2018, having never been a fan of working out in a gym. I immediately loved the place. Ken and Tiffany are fantastic, and it feels like I am getting a personal training session at every class. Their equipment is fantastic for obstacle course race training, and they incorporate exercises that I had previously not thought to do on my own. They have created an atmosphere in which you want to push yourself to the next level and encourage you to do that every day. The community atmosphere they foster is fantastic. I highly recommend this gym.

Erik Arena 5 years ago

Fantastic experience: I am extremely excited to be a part of The Endurance Factory (TEF) gym. I was just beat with the daily grind of work, commuting to/from work, home, and family routine every week and needed to make a change to take care of myself. I walked in to the TEF In April of 2018, met with Ken Peluso and literally said “l need your help” and he turned me over to Tiffany Palmer. In 2018 I completed 6 Spartan Sprints and immediately got hooked on being fit again. Both Tiffany and Ken are tremendous athletes that will coach you to a being a better human no matter what fitness level your at. What I love the most about the TEF is the fun family of people I work out with and the variety of WODs that the coaches prepare. Everyone one is super supportive and always encouraging you during the workouts.

Ama P 5 years ago

Fantastic experience: Love the Endurance Factory! What makes it special are Ken and Tiffany. I have never seen people more committed to helping their people succeed. They have a can do attitude, and so do all the athletes who train here. I've never been part of an actual community, and it's so lovely to be with others who are also supportive. Ken and Tiffany are excellent coaches, showing you exactly what to do and how to refine your skills, no matter how complicated the movement. I used to work out at another HIIT/ocr focused gym in DC, and dumped them when I realized TEF had really great functional fitness workouts where I could do serious strength training. I also tried a bunch of crossfit type gyms that were way too screamy or would push people into dangerous situations. TEF has really challenging workouts, but they take the time to show you how to do what you need to know, and coaches Ken, Tiffany, and your fellow athletes really are fantastic motivators while you're doing them.

Sandy Bass 5 years ago

Fantastic experience: For 5 years I've been searching for a gym where I could find people to help motivate me and support me to not give up. From my very first introductory class I felt that support and motivation at The Endurance Factory. It's easy to walk into a new gym and feel nervous, confused and scared. To be honest I felt that way walking into The Endurance Factory, it was something new and it was something scary but that feeling went away as soon as the class started. The other members pushed me and encouraged me the entire class; high fives coming at me from every direction and words of encouragement to not give up. If you are looking for encouragement, support and education on proper technique so you don't injure yourself than The Endurance Factory is the place you need to check out. I've tried every gym aspect over the past 5 years, at home workouts, $10 a month gyms, $500 a month trainer and NEVER in the 5 years of trying everything else has anything come close to what I get at The Endurance Factory. I've found my gym home.

Heather Nunn 5 years ago

Fantastic experience: I absolutely could not recommend this place enough! Ken and Tiffany are amazing, they meet you where you're at in every workout. I have learned so much about the mechanics of good form, and after taking Ken's 28 day challenge in January, I learned about the best nutrition to fuel my body and achieve my fitness goals. The environment at TEF is welcoming and supportive, everyone is so friendly and cheering you on in class. I have not only gotten physically stronger from working out here for the past 10 months, but mentally as well. I took Tiffany's OCR prep course prior to my first Spartan race and loved it! All the work I had put in at TEF prepared me well and the Spartan Sprint I did felt easy. :) The workouts are tough but you will be glad you did them! A great place with great people!

M H 5 years ago

Fantastic experience: Over the past 10 years I’ve been to multiple gyms including Crossfit \ HIIT \ Boxing \ OrangeTheory. This type of workout is just my preference as you get a coach for every class, you never have to program, and you get a great mix of cardio \ strength across the programs. This is the exact type of workout the endurance factory (TEF) offers. I break down my ‘rating’ into 3 categories 1) Do they incorporate barbells – Yes/No. The Endurance Factory does, and for me it’s critical. Places that have strength w/o barbells I found lacking in delivering results. And personally not as much fun. 2) Coaching – Personally I entered the ‘Crossfit’ world at a gym in howard county that was being run by recent college grads. Not to disqualify any coaches based on age, but when you are using barbells technique is critical, or you can be seriously injured. I left that place b/c I knew the coaching was severely lacking. That said I’d trust Ken \ Tiffany to teach one of my friends around this type of training. I’d certainly recommend an intro \ 1:1 program to get comfortable with the movements. They pay attention to everyone in the class, and more importantly classes are capped! This is critical b/c a coach can only pay attention to so many people in a class. If you have 35 people and 1 coach you won’t get much ‘coaching’. I’ve been to places that allow far more people in classes with a single coach. That should be a warning sign. 3) Cost \ Flexibility – For me this is a very important component. Many of these types of gyms tend to combine services \ programs where you are paying a high fee for special classes you may never use. Or they have tiered programs where the affordable levels don’t give you access to the classes as often as you would like to go. TEF keeps it simple with the unlimited plan, and has special classes you can choose to purchase if you think they would help. Finding a place with great coaches at a fair price is why I gave my rating. I think this gym is the perfect mix. Downsides – I’ve been to places with included technology tracking (tools like wodify), or nice locker rooms \ showers. Even to a couple of places that have A\C for the summer. These features are nice, however I’ll take the quality coaching \ fair price over the extras. Other considerations – TEF is a gym that does have the majority of the members (50+ %) enter into obstacle races. There’s still plenty of people that go just to work out, but if spartan races interest you there’s plenty of like minded people to help strategize. Best of luck with your search!

Vanessa Santiago 5 years ago

Fantastic experience: LOVE the gym!!! TEF is an amazing place to work out!! GREAT ambience, clean place, positive attitude, good hours, wide range of programs available, friendly and family oriented. Just try out, you will love it too. My husband and I discovered the place a year ago after my sister started working out with them. Ken Peluso and Tiffany Palmer are excellent coaches and they are always aware on how to do the workout and checking on you if you don’t have a good form, that’s really important for me and my husband because that decrease the chances of getting injured. TEF have created a strong and motivational community that allows every individual to achieve their maximum potential within their physical capabilities. With that said “TEF is the place for everyone: from beginner athletes to elite athletes and more than a community is a FAMILY!”

Andres Carriedo 6 years ago

Fantastic experience: This gym is family owned and operated and the family vibe resonates through the building's pores (yes, cinder blocks and drywall have pores). When you come in, you are welcomed not by a sales pitch, but by coaches who genuinely want to help you get stronger and more confident. Like many of the people who joined The Endurance Factory, I was looking for a place to train for Obstacle Course Races. If that's your thing, this place is perfect. I had a goal to do the Spartan Trifecta in 2018, but I also wanted to do fewer burpees in races. Both Ken Peluso and Tiffany Palmer are world class obstacle course racers who love to coach and pass their knowledge on. The Boot Camp classes are varied and challenging for all levels. I started out pretty out of shape and have worked my way into being pretty fit over the course of the year. Even with the loss of 25 lbs. I describe the classes the same way. They're challenging, but doable. Ken and Tiffany don't let you dog it or fail. They get the most out of everyone. There are tons of gyms in the area. Many of them have great coaches who will help you get stronger and give you personal attention. However, for me, four things set The Endurance Factory apart from most of those gyms. First, the owner, Ken Peluso, is my coach. He knows my race schedule, my injury history, my targets and goals. He knows how to get me where I want to go. All I need to do is show up and put in the work. Second, the gym is welcoming and family oriented. Everyone is welcome. Kids can train with their parents or hangout with the other children while their parents workout. Experienced racers workout beside and encourage first timers and non racers. The regulars are friendly and everyone is welcomed their first few classes. Third, we all work hard, but we also have fun. Tiffany Palmer is an elite obstacle course racer and one of the coaches. She pushes us hard in class, but she incorporates games to make the workouts more fun. Fourth, the gym also hosts potluck cookouts and has added perks to the membership package like Sunday morning Yoga classes and meal plan options. These are things that members want and ask for. They aren't just read or heard and "taken into consideration." They get done. I'd never been one for strength training before joining The Endurance Factory. Lifting weights is a new thing for me. I joined on Opening Day because Ken didn't get pushy with his sales pitch. He told me what he planned to deliver to members and showed me how I could benefit from the facilities. That was good enough for me to give it a try. It's now 10 months later and Ken has delivered on everything that he said that the gym would be. He's also been a great coach who has helped me through injuries and in the process helped me build confidence in my abilities. And I'm not the lucky, special one. Everyone at The Endurance Factory gets "the lucky special one" treatment.

Breanna Appleby 6 years ago

Fantastic experience: When I first learned about The Endurance Factory I honestly didn’t believe it was a gym for me. I don’t run. And I definitely have never done an obstacle course race. But then Ken started promoting the Strength In Numbers program and I figured I would give it a shot. Best. Decision. Ever. Not only did I learn about the importance of strength training from a coach who is so invested in the success of his students but also developed friendships with women of all fitness levels. Since joining The Endurance Factory, I have more confidence not only in what I can do at each class but when I can accomplish in my daily tasks. Things I never thought I could accomplish I now have goals to sore past. The classes are designed to encourage success in everyone. The coaches are supportive and enthusiastic about what they do. They have truly created a family out of everyone to comes into the gym!

Clint 6 years ago

Fantastic experience: The Endurance Factory is awesome, it offers a unique training experience that you can't really get anywhere else. Ken & Tiffany are fantastic trainers, they're knowledgeable, tough, but very nice & encouraging. You can tell they love what they do and are very passionate. I can't recommend The Endurance Factory enough!

Ashley Smith 6 years ago

Fantastic experience: The Endurance Factory is a community of incredible human beings. My husband and I originally joined to prepare for a Spartan Trifecta, but it didn’t take us long to realize we would be here for much longer. Ken and Tiffany are incredible coaches who genuinely care for their athletes. It is a welcoming atmosphere where all are pushed to succeed. They work with people at levels and points of their fitness journey. If you have a goal and are willing to work hard they will be behind you 200%.

Brittany Urso 6 years ago

Fantastic experience: I discovered The Endurance Factory through Groupon last May and thought it would be something different to try to get in shape and improve my health. I was nervous because I am not very athletic and I didn't know if I would be able to keep up. It has been 6 months and I am so glad I have stuck with it! Ken and Tiffany are both fantastic trainers who will support you and help you reach your goals no matter what they are. I am usually intimidated when working out in group settings because I am worried about being judged by others who are more fit than me. I have never once felt that way at TEF. Everyone has been so welcoming and encouraging since day one. If you have tried traditional gyms and have been unsuccessful I would definitely recommend The Endurance Factory. They will help you get the results you are looking for in a supportive, positive environment!

Miranda Riley 7 years ago

Fantastic experience: Whether you’re looking to spice up your usual workout routine or train for your next big OCR race, The Endurance Factory is a place that you should check out. The owner, Ken, and his family are so kind and passionate about what they do. Ken is an expert on endurance sports and injury prevention so you will be in good hands. There is everything you need here- clean workout area, top notch equipment, crazy fun obstacles, and one of those water bottle machines where the water magically comes out without having to push any buttons!! Everyone is so friendly, you’ll definitely find yourself in some good company.
