F45 Training North Thornton: Opinions

Fantastic experience: This place got me back into a gym routine! The workouts are so fun yet challenging and the coaches are incredible!
Fantastic experience: I just joined this gym and wow! I am definitely hooked on the workouts here, so many variations and the coaches are great and will challenge your strength. I would absolutely recommend this place!
Fantastic experience: I have been doing a boot camp (Camp Gladiator) and spin for years while I was home with babies and traveling. This has been the best jump start to my post body baby and at the age of 40. Everyone can do this workout. I see people that could run marathons and I see people like myself that are struggling but getting through. Shane is the head trainer and I recommend everyone speak with him on your goals. He’s excellent-
Fantastic experience: F45 northern Thornton is the best! It’s clean and the staff are super friendly. I always look forward to the classes, even the cardio days!
Fantastic experience: I've been with F45 for over 3 years now and I've been at F45North Thornton for 1.5 years. This is my favorite studio! The space inside is vast for a studio gym, but my favorite part is how the trainers are consistently challenging you to do more whether it be to go for one more rep or increase the amount of weight you lift. I value that push because they see in me what I sometimes don't see in myself. They are also really good about giving you alternate exercises when you are dealing with an injury. I love F45 and I love F45 North Thornton more!!
Fantastic experience: Finished my 11th class today. Coaches are great, the support from the rest of the members is awesome. Doesn't matter what shape you're in to start, there's something to be gained for everyone from this type of functional fitness experience. Highly recommend.
Fantastic experience: For years i was a “weight room” only lifter, and didn’t understand why someone would go to scheduled classes. Then I tried F45. Holy sweat. I was able to drop 10% body fat in 3 (dedicated) months! I absolutely love the ability to go in and just shut my brain off and let the trainers tell me what to do. There’s comradely with other members as we are all in the same boat. There’s a sense of belonging. And best of all, the trainers constantly push me to be better. Example: “this time instead of jumping onto the box, let’s jump totally over the box” I’m always looking for that next challenge, but this place is for all skill levels. Even when injured the coaches have been able to provide me modifications so i don’t have to miss a beat. Honestly, give this a shot. It’s fantastic.
Fantastic experience: F45 is the best gym I've belong to yet! The coaches at this location always push us to add more weight or to just keep going and I love that! Sad to see some of the great ones leaving though because they become your gym family and you look forward to seeing their cheerful faces every day!
Fantastic experience: Great gym with a team like atmosphere. Coaches are there to help guide you and push you to the next level. F45 is the best 45 minute workout!
Fantastic experience: Absolutely love F45 North Thornton! The trainers are so fun, the music is a vibe, and the workouts are intense in the best way possible!!
Fantastic experience: This was just a trial class for me, but coming from a former bodybuilding world and anti CrossFit world, it's a good mix in between. The great way for somebody that has limited time in the gym to be able to get both cardio and strength training into one efficient workout! The coaches were knowledgeable, friendly, and great at making sure I understood the movements and was performing them safely!
Fantastic experience: Absolutely loved this place. I had never done f45 before but I’ve basically tried everything else. The training was awesome, staff were great and facilities were top notch. I worked out for one hour and couldn’t believe how fast it felt. Normally workouts drag; not this one. I’m hooked.
Fantastic experience: I have been to several different f45 gyms and this has to be one of my favorites. The coaches are incredible and have such great energy all the time. The facility itself is beautiful and well maintained. Absolutely would recommend!
Fantastic experience: This place is amazing and very challenging! The trainers are all so friendly and push you to your limits! The gym is very clean and equipment is in great shape! If your sick of going to the gym and need a change this place is for you!!! I could’t recommend it more!
Fantastic experience: Positive: Professionalism , Quality F45 is a great 45 minute workout, the workout moves so quickly that you don’t even realize the time. I love the mix between strength and cardio days. The coaches are amazing and push you to do better on form or go heavier on weights. Highly recommend this group fitness in Thornton!
Fantastic experience: I love this gym. I was super nervous the first few times I went, but I absolutely love this place. They helped calm my nerves and gave me the confidence to keep going. Now I look forward to going to the gym everyday and try not to miss going. The atmosphere is fun, and the trainers are super positive and helpful. The workouts are fast and challenging but you feel very energized afterwards. I highly recommend F45. Whether you are new to working out or in shape this is definitely a place to try.
Fantastic experience: I've always been a gym person but never done team or functional training. I took the trial to test out how I'd like it and was not disappointed. The vibe and people in the early morning classes are fun to workout with and everyone inspires each other, I've never been around that but love it. The trainers help give advice on form and alternatives if you have injuries or soreness, and help to motivate in the sessions.
Fantastic experience: F45 North Thornton is an exceptional gym. The coaches truly care about their members and go above and beyond to create a welcoming environment. I highly recommend F45 North Thornton to anyone looking for a gym with a supportive community!
Fantastic experience: I love this studio!! I did a 2 week trial and ended up joining! The coaches are very motivating, friendly & professional. Over the last couple of weeks my strength and endurance have improved. Christine and Marlena are very energetic and never let me slack! The workouts are always different and never boring. Definitely give this a try, if you are considering!
Fantastic experience: This gym is for everyone! Want strength? What endurance? What core? Want agility? Every class has something for everyone, no workout is ever the same so you won’t ever get bored! The coaches are super helpful with modifications and come with loads of energy. This is the type of gym that turns into a family, I can’t recommend it enough!
Fantastic experience: Can’t say enough good things about this F45 Thornton team. I’ve always been a person that despises working out and doesn’t know what the heck to do at the gym! Starting at F45 I was nervous but on my first day Trainer Holly made me feel right at home. No matter how many times I do some workouts wrong Trainer Kristi corrects me with all smiles and encouragement. Trainer Collin has great uplifting energy that makes it fun to be there. Trainer Josh is an amazing motivator and coach that wants the best for everyone in the gym!!! I honestly didn’t think I’d like going to the gym this much until now. It is a fun place to get your mind off all the stress you might have at work and home. I 10/10 suggest everyone to go here it will improve your body mind and spirit, leaving you wanting more
Fantastic experience: Positive: Professionalism , Quality I have never been a gym person, ever but since coming to F45 I have felt better, had so much fun working out and love the accountability and the coaches enthusiasm and assistance through each workout. If you are looking for a welcoming, fun and great workout experience, then this is the place to go! I LOVE it!
Fantastic experience: I absolutely love F45 North Thornton! I happened upon their 2 weeks for $2 special and have never looked back. The space is huge and there is a lot of room to spread out. I think the energy is high and the trainers are so helpful and enthusiastic. They make every class so fun…especially when you get them singing and dancing! I’ve met a lot of great people through F45 and I would recommend this place to anyone and everyone!
Fantastic experience: I love F45! It’s a fantastic workout with encouraging trainers & wonderful community! So happy we decided to join the F45 fam!
Fantastic experience: What a great workout! I’ve been apart of many gyms over the last 12 years. The community F45 N Thornton has created is what keeps you coming back. The coaches feed off each others energy which makes it fun. I have to tip my hat to Lauren the manager for creating a great culture and selecting a great team! Come and see…You won’t regret it!
Fantastic experience: Positive: Professionalism , Quality F45 is an awesome workout! I love the combination of strength and cardio, especially having one day a week devoted to upper body and one day a week focused on legs. I can tell I am getting so much stronger after 50 workouts! The coaches and staff are great and really motivate me to lift heavier and push myself.
Fantastic experience: Positive: Communication , Professionalism , Quality I am absolutely loving my experience at F45! The instructors are amazing and keep you motivated! The faculty is always clean and the class times are convenient!!! After my two week trial, I was so motivated I decided to become a full time member! It’s a perfect way to get out of the house and work off a little energy!!!
Fantastic experience: I love the class setting with each day’s workout being completely different and with a varied focus each day of the week. The staff and coaches here are super friendly and caring. It’s obvious they love working at F45 and you’ll usually see them in class on their day off! Whether you’re looking to get back into it and change your body composition and/or lose a few lbs, or you’re looking for a place to make new friends and stay in shape together, this is the place!
Fantastic experience: This f45 gym and these trainers are exactly what you’ve been looking for. I’ve hit over 100 workouts at this gym this year & I can’t believe it. The workouts are a mix of both strength and cardio and they are all equally as hard and fun as one another, during the 45m workout you put it all out on the table when your in there because the trainers push you to do more, it’s almost like you have a personal trainer for any corrections or words of encouragement to push you through the class. The members are equally as amazing & I can’t suggest anyone to try f45 enough.
Fantastic experience: I love how I don’t need to think or plan to get a 10/10 work out in! Everything you need is right in front of you, and the balance between cardio and strength is spot on. I love how everyday it’s something new so your mussels and brain don’t get used to the same work out over and over again. F45 keeps it exciting and fun! The coaches keep you motivated and provide critiques that help improve your form without killing your vibes.
Fantastic experience: I absolutely love this place. I’ve been working out for years and have always loved going to the gym. However, I found myself in a rut and the sets and reps were getting boring. I never thought of myself as a “class” person, but thought I would give F45 a try. From the first day, the trainers were welcoming and friendly, and the classes were challenging and all the exercises I wouldn’t do on my own, (which is why you should do them right!?) I recommend and brag about this place all the time! You can’t go wrong, whether you’re a beginner in the gym or have been around the block, this place is for you!
Fantastic experience: This gym has been such a lifesaver after getting very off track with my fitness during the lockdowns. The workouts are always different and challenging and can be adjusted based off your fitness level. The trainers are also very helpful and encouraging! By far my favorite gym I've ever gone to.
Fantastic experience: Positive: Professionalism , Quality Just joined this gym recently and I absolutely love it! I was never much of a HIIT kind of person and this place really takes the thinking out of my workouts. The trainers are encouraging and up-beat. I look forward to going to the classes every time!
Fantastic experience: F45 is a great workout and the trainers at North Thornton are encouraging, helpful, knowledgeable and friendly. They made me feel at home when I joined and they push me every session to give my best effort. I highly recommend this gym to anyone looking for a great overall workout including cardio-focused days, weights-focused days and hybrid days with a mix of everything.
Fantastic experience: If you’re looking to get in the best shape of your life, check this place out! Every workout will challenge you but the rotating format means you’ll never get bored. The trainers are amazing - they motivate and support you the whole time and have mods for any injury or concern you might have. Clean gym and spaced out stations ensure enough room to workout and stay socially distanced. Whether you’re looking to start your fitness journey or take it to the next level, this is the place for you!
Fantastic experience: I joined F45 North Thornton after I tried a few of their bootcamps prior to opening. I was looking for something to break up my normal strength training and I was sick of traditional cardio. I am an early bird and the 5:30 AM classes have been perfect for me to get my workout in and be home in time to get the kids day started. All the trainers are great and the workouts and music are a great variety and mix. I love the HIIT style and love that by the time I think I am ready to quick, I've already completed my workout!
Fantastic experience: Positive: Communication , Professionalism , Quality F45 has been "Life Changing" for me! I've been in search of a gym of this type for a few years. The trainers are AWESOME and motivate you to at least try an exercise but then offer modification to build muscle to get to the next level. I feel at home with F45!!
Fantastic experience: Being used to a traditional gym setting I was skeptical of the class structure they have, but it turns out is exactly what I need to get my body back where it needs to be. The trainers are professional and the exercises change daily, so it never gets boring. I did the two week trial and decided to stay on. It’s now part of my daily routine.
Fantastic experience: If you're wondering what F45 Training is, just visit the corporate website and they do a great job of explaining their workout strategy and what to expect. But I came here to tell you why F45 Training North Thornton is special, not only will you get an incredible workout at one of their many class times that can fit almost any schedule but you'll get actual caring instructors who know your name, offer modifications for your specific needs, and aren't afraid to have fun and make you laugh. The workouts will challenge any fitness level and the coaches energy always matches the music's hype level. F45 Training North Thornton has helped me take my fitness to the next level and they can help you too!
Fantastic experience: Positive: Communication , Professionalism , Quality If you’re looking to have fun, lose weight, tone up, and build muscle F45 in Thornton is the place to be! The workouts are very organized and the trainers are supportive, fun, and motivating. It’s a great environment and we are excited to have you.
Fantastic experience: I did a 2 week trial here on a whim and from the very first class I was hooked!! There are so many great things about the workouts, and this studio in particular. I love how you do different exercises each day, with each day also having a different focus. This keeps me so engaged throughout the week. As far as the studio goes, the trainers here are exceptional. Each trainer makes strong efforts day in and out to bring the energy, remember every single name, and give out all their encouragement/expertise. F45 workouts are HARD, and this studio will make you want to keep coming back for more.
Fantastic experience: I can't begin to say enough good things about the F45 studio in North Thornton! The staff at F45 exemplifies professionalism while displaying exceptional knowledge of personal training and health and fitness education. Not only do they constantly make you feel welcomed every time you walk through those doors they find new and exciting ways to encourage you to reach your fitness goals. First time gym go-er, no problem they will work with you step by step to build the confidence you need to succeed. Highly active looking for more, they have that covered too as they will challenge you to push yourself to new levels of your training.

Fantastic experience: I have been doing F45 since May and it has been the best choice I’ve made. The environment, the coaches, and the community are so welcoming and inviting. F45 and the coaches meet you where you’re at and push you past that place. They are always finding new ways to push you, encourage you, and support you. F45 North Thornton coaches get to know you and learn how you work best. Not only do the coaches make you feel welcomed, the community that F45 has created goes beyond that. There is competition amongst the welcoming and judgement free zone. I feel the healthiest, strongest, and most confident that I’ve felt in the longest time and I owe it to F45 North Thornton, the coaches, and the community. I will recommend F45 to everyone I know.
Fantastic experience: F45 North Thornton provides the most incredible workouts, excellent trainers and a sense of community with all the members. I have never enjoyed group fitness classes until I came here. The trainers and members help push me past my comfort zone, which is exactly what I’ve needed in order to reach my fitness goals. The workouts consist of cardio, resistance and hybrid exercises, so there is never a boring class and they go by insanely fast. I am officially addicted to F45 and would recommend it to anyone looking to reach your goals.
Fantastic experience: I absolutely love F45!!! The workouts are challenging and mindless. You walk in and everything is set up for you to crush your workouts. For me, the best part of working out at 5:30AM when my brain is not ready to function is not having to think about what I am doing. I just follow along the trainers instruction and step by step videos that are displayed on multiple TVs throughout the studio. This workout style is perfect for all levels of fitness enthusiasts. There is a strong community of people you workout with that have the same goals as you. We are all motivated to live an overall healthy lifestyle. The monthly challenges are another great motivator to stay on track. The trainers are AWESOME! They are fun, encouraging, and professional. If you ever have a question about form or function they step right in and address it. Plus they have some pretty sweet dance moves. I couldn’t recommend this gym more!

Fantastic experience: I always look forward to coming to classes here! The instructors and workouts are hard but the time goes by so quickly while you’re pushing yourself in ways you wouldn’t if you were at the gym by yourself. A great environment for getting stronger!
Fantastic experience: F45 is a fantastic option for those who have specific fitness goals, but no clue how to attain them. I have had several gym memberships, but gyms can be so intimidating. F45 classes have a multitude of exercise variation with lots of different equipment. It's fun, accessible, and challenging, no matter what your experience or fitness level. Trainers are helpful, silly, and so genuine. I'm ecstatic to be part of this F45 community!
Fantastic experience: In the past 15years I have tried many fitness gyms (CrossFit, OTF, personal training, yoga, p90x). In those years I’ve dealt with injuries and had to quit those programs or they weren’t getting me the results I desired. F45 gym is the perfect mix for my body and the personal trainers are awesome at guiding the group training and helping with modifications when needed. The workouts are challenging and fast paced but don’t seem to go on forever, I love that most are 45mins and always incorporate abs and stretching. My body is already positively changing in just 1 month. I can’t wait to continue my journey here as this gym community grows. Welcome to the neighborhood F45 North Thornton, we’re all glad you’re here!
Fantastic experience: Positive: Communication , Professionalism , Quality I love F45 North Thornton! I always walk out of there feeling accomplished. The coaches are very friendly and motivating which makes a big difference! F45 workouts are challenging yet fun and the best part is that they’re only 45 minutes so you get in and get it done right. I would recommend F45 to all!
Fantastic experience: I waited months for this gym to open post COVID and it did not disappoint. The coaches and members have the best energy which will keep you coming back for more. Every class is different and all the movements can be modified to your skill level. It’s only been a few months and I can already see myself losing fat and gaining muscle!
Fantastic experience: Positive: Communication , Professionalism Thank you for welcoming an AZ F45 member and coach during the holiday break! Was so happy to get in my favorite workouts while visiting family in Denver. This studio is beautiful, the equipment is on point, members pushed themselves in each set, and the coaches were great
Fantastic experience: I absolutely love this place! All of the coaches are OVER-THE-TOP! They are passionate about coaching, they are supportive, engaged, fun, and charismatic. I love the work hard play hard environment. The workouts are challenging and always kept fresh (changing every single day). The coaches regularly schedule meet and greets to get to know the coaches and other gym members. The gym atmosphere is super welcoming. I can't say enough good things about this gym.
