Mountainside Fitness Surprise: Opinions

Fantastic experience: Realistically, people usually only write a review after they had one lousy experience, simply forgetting all of the other memorable and great times. If it's not a bad review, then the guest must be anxious to promote the business in question. Any other reviewer (3 star range people), usually just have too much time on their hands. I happen to be the reviewer who had a fantastic time coming to this gym. Now of course when you go to Mountainside fitness you are bound to see a bunch of punk, pretty boys; the city is full of old people so the kids who aren't smoking pot are at the local gym getting ripped to feel as if they are their on-screen role-model. Aside from the punks who take 10-minute breaks at this gym on the bench because they are doing too much weight to begin with/talking with their friends, there are actually some pretty cool people here. You will feel comfort in joining this gym mainly because of the excellent staff. They always check you in and give you what has been lost in society; eye contact, as well as wishing you a great workout. The staff is always willing to educate newcomers on how to train and will work with you on your own fitness plan. If you want to go to a gym that has a staff that makes you feel as if you're at home, I'd definitely recommend this Surprise location of Mountainside to you.
Fantastic experience: My son and myself we got membership here about a year ago. It’s always clean and run by friendly staff . We recently canceled because my son wanted another fitness club only because they have a pool . However if you look for a great gym club with best cardio machines . This one is the best in Surprise area, you and you won’t be disappointed .
Fantastic experience: The childcare at Mountainside is phenomenal. All of the girls are great with our 9 month old son, he’s always so excited to see them all! They really make us feel like family and give us the peace of mind that our son is getting the best care while we get our workouts in. The facility itself is set up very well, we never have issues getting use of the equipment we need, and always lots of cardio options. Our family will continue coming to Mountainside for years to come.
Fantastic experience: Great gym, always clean, great members and staff. Have always been impressed with all of the variety of equipment and workout options that this gym has!!
Fantastic experience: I just recently signed back up with Mountainside Fitness. Tina was helpful in signing me up and making sure I had the time to make sure my child was comfortable in the kid care. My biggest shout out goes to Taryn in the kid care area. She was the absolute best in helping my child to feel comfortable. She helped my child release her fear of coming in there. That's what my child said! It really was very special and you never know how much your patience and kindness can help shape and support our future kiddos. So much gratitude! ❤️ now I get mommy time with no worries! Thank you Taryn!
Fantastic experience: Really clean and a good atmosphere there. The staff is really nice. Out of all the locations surprise is my favorite one mainly because how spacious it feels.
Fantastic experience: The best gym I have been to in a long time. Everyone is very helpful. Lots of room.
Fantastic experience: Great gym with lots of friendly staff. The personal trainers are stellar and the childcare staff are so great!
Fantastic experience: We love MSF Surprise! The manager and his staff are incredible. They keep gym clean and are always friendly. Incredible customer service!
Fantastic experience: I've been working with Troy S. for 8 months now and it is probably the most fit I've ever been in my life. Troy makes the time fly by. He has figured out the way to make working out fun. The entire staff has been fantastic in taking away the nervousness of being a novice in the gym. Would recommend to anyone.
Fantastic experience: Mountainside gym in Surprise is a clean, well run gym with friendly staff and a wide variety of classes and equipment to access. The best part of this gym, for me, is my personal trainer, Troy. Troy has helped me to achieve my fitness goals and has taught me how to maintain those results! He makes me accountable without judgement and adapts the workouts easily to whatever limitations this 66 year old woman requires! I look forward to my workout sessions with Troy and. Grateful to him!!!!
Fantastic experience: I love this gym! Clean, friendly staff, lots of equipment. I especially love my trainer Troy. I started working with him in August and through our in-person workouts (and workouts he texts me for the other days of the week) I've gotten stronger and more fit than I have been in quite a while. He's great at designing a program to help you reach your goals, and just when you think it might start to get easy, he changes it so you continue to be challenged, and get stronger. I've seen him work with young athletes, and 'active agers' who want to stay healthy into their retirement. He customizes his workouts for each client -- no cookie-cutter approach here. If you need a coach who pushes you, challenges you, but also recognizes when it's time to dial it back a bit, Troy is your guy!
Fantastic experience: I have been training with Troy for over a year now , when I first met Troy we had a goal in mind for me , with his professional knowledge of weight and strength training we surpassed my goal . If there is anyone looking to better themselves mentally and physically I would recommend scheduling an appointment with him !!! He writes my workouts for me and a strict meal plan to follow he's one of the most curtious and professional people I have met . Thank you for all you do Troy
Fantastic experience: I highly recommend Troy as a fitness trainer. He helps you reach your fitness goals and adapts the training if you have injuries. He recommends a program for you to complete on your own also. 5 stars!
Fantastic experience: Positive: Communication , Professionalism , Quality I’ve been going here for almost 5 years and honestly I couldn’t ask for a better gym. Updated equipment, clean facilities, friendly staff, not overly packed, and decent membership prices. I would definitely recommend if you’re looking to join a gym.
Fantastic experience: I've only been a member for a week now but I've had a great experience with the staff. Friendly & knowledgable people, simple membership program, and the complimentary personal training session I had with Anthony was awesome! Would highly recommend.
Fantastic experience: Great gym, always clean, great variety of equipment & classes. Personal Training was a main factor in my selection of a gym when I joined. I've had trainers on & off over the last 10 years but getting paired up Troy Sienkiewicz at Mountainside, Surprise takes the gold. He is very professional, kind, and knowledgeable but the results I've seen over the last several months are amazing. He holds me accountable, educates on form, and pushes me hard every session. He really takes the time to know & understand his clients, their goals, and what drives them. Mountainside is lucky to have him.
Fantastic experience: Wanted to join and had thought about it. Stopped in while I waited for our dog to finish his grooming appointment in the same center. Wish I could remember her name, but a young lady asked if she could help. I told her what I wanted to do as Mountainside location was a good fit as I had to take my mother-in -law to day care nearby. She took my information and then searched for the health plan membership option I had available. She found it and I enrolled. She was fast, efficient answered questions and took care of my need in less than 15 minutes. She offered to give me a tour but I told her I had a tour previously and have used the massage at Mountainside. All in all the welcome and service was impeccable. How nice it would be if every service person was as well organized,. welcoming and efficient in meeting a clients needs. Bravo to Mountainside for hiring this young lady and Bravo to her for making a new client feel well served. Regards,' David Streilein
Fantastic experience: We are so happy that we found MSF! The staff are very friendly and helpful. The whole facility is clean and organized. The gym never feels crowded and we always have the equipment we need for a great workout without having to wait our turn. We really appreciate all the various areas that make different styles of workouts easy to complete. We highly recommend this gym. Thanks for a great experience.
Fantastic experience: Positive: Communication , Quality I've been working out here for over a year and half with my physical trainer Troy. He's amazing, knows my strengths and weaknesses. I would highly recommend him to anyone who wants to get in shape even for us ",old"guys.
Fantastic experience: I have been a mbr since 2010/2011 and have had Troy Sienkiewicz as my trainer off and on since. I have tried other trainers at different gyms as we are seasonal residents and none compare to him. Mountainside Surprise is an overall great gym...I love it! The classes are fantastic. And the instructors are the BEST! If not for the instructors (Evenstar just to name one) and trainer Troy I would not be in the condition I am in today. Thank you all and thank you Mountainside for the great EEs you have working for you.
Fantastic experience: Positive: Communication , Professionalism , Quality I have been working out with their personal trainers for about 2 years. I have worked with Troy for over a year. I have lost over 40 lbs and have gained strength and coordination. Troy is an awesome motivator. Thanks Troy.
Fantastic experience: Positive: Communication , Professionalism We have been going here for 2 years, my daughter has been going to the daycare for most of her life and she loves it. She runs in with a smile on her face every day. All the girls are awesome! We love it!
Fantastic experience: Positive: Communication , Professionalism , Quality Troy S. personal trainer is the best there is !! Might be time to give him raise (take in to serious consideration)!! Have seen insane results in the matter of three months working with him. Now everybody wants to train with him. Super dedicated & cares about his clients! Way to go MSF
Fantastic experience: Lexi made our initial visit easy and painless. She took time to show my husband and me around and we joined on the spot. Locker rooms and group class rooms were spotless and all the equipment well maintained. There are an abundance of classes to meet any fitness level. We were there mid day and not very crowded. We’re looking forward to using the facility and know we’ll enjoy working out together there.
Fantastic experience: Nice and clean gym with lots of amenities. Really fun that they have a rock climbing wall at this location.
Fantastic experience: Thank you Lexi for getting us signed up so quickly! She explained in detail how the membership worked and was also prepared to answer all of my off the wall questions. I have used the gym 2x so far and really enjoy that it is not overcrowded and most of the equipment is in working order. I was recently a member at a competitor and that was not the case...
Fantastic experience: My husband has been working with personal trainer, Troy Sienkiewicz, for over a year now. He has really been personally invested in my husband's progress and pushes him to do better each and every visit. You can tell he really cares for the individual to have success, not just during his training sessions, but for a lifetime. I, personally, love when he has hubby work on the dreaded "wall" - gives him a sore Gluteus maximus ;) Highly recommend Troy as a trainer if you are looking for someone to provide guidance with care and passion.
Fantastic experience: Mountainside Fitness is clean and has the best trainers/instructors! Troy Sienkiewicz is the BEST personal trainer! I was so excited recently to put on shorts when those same ones a year ago would not go past my thighs-those are real results! He pushes me physically but recognizes my limits. He holds me accountable to a fitness plan which is frequently updated as progress is made. Thanks to him, over the past year, I have gained strength, lost weight, and decreased my cholesterol. Troy’s methods produce measurable results! His expertise and encouragement is worth every dollar. Also, Yogi Gail Butchart is an amazing instructor! Love her yoga classes, especially the yin yoga and restorative yoga. Her classes have a beautiful energy in them. I leave the class feeling more peaceful, relaxed yet more energetic. She helps you modify the poses, if needed, to fit your abilities. You can tell that Gail fully enjoys teaching yoga.
Fantastic experience: I've been going to this gym for over a year now. I signed up for Personal Training and started working with Troy Sienkiewicz. He is the BEST. Motivates, keeps me on track, pushes me and most importantly cares. I highly recommend personal training from Mountainside Fitness. It's an investment in myself that is very much worth the cost. Thanks Troy.
Fantastic experience: Positive: Communication , Professionalism Senior getting back in shape after a year sitting at a desk starting online business. Ben listened to my concerns, and my physical limitations were taken into account. Going to be easy (but tough) working with him. Facility has everything you could ask for (including a rock wall I will NOT be climbing), and all is pristine!
Fantastic experience: Positive: Communication , Professionalism Super clean environment, plenty of parking, and excellent customer service. I actually joined because the steam room is the most fabulous feature! My skin is ecstatic! Can’t wait to try out all the fitness classes. You should join. Definitely the best in our town.
Fantastic experience: Troy S. Is an amazing, fantastic trainer! I have done decades of weight-training but when I broke my shoulder it was difficult to work out without reinjuring myself. So I began working with Troy! What a difference he’s made in my life. I’ve been working with him for almost two years despite the pandemic and he is always enthusiastic, highly motivating, and makes working out fun! I love the fact that no matter what physical issues I throw at him he can always find a way to work around them (I have fibromyalgia which sometimes results in various aches and pains). I also enjoy talking to him during workouts about sports, especially the NFL. I have to say that Troy is one of the best trainers at Mountainside. His enthusiasm makes me work harder and the results I have achieved are amazing. He is probably Mountainside’s most valuable asset and thus the MVP! I love my workouts and might not have stayed at Mountainside if it hadn’t been for Troy. Remember MVP! - A. Kilstofte, Ph.D.
Fantastic experience: My family has been coming to this gym for over 8 years. Decided to make a change to go to another gym in the area for a little savings. Long story short turned back to Mountainside fitness. The grass is not always greener on the other side. Especially when it comes to customer service and feeling welcomed and stress-free when you leave the gym. The staff is great at Mountain Side. Always make you feel welcomed. Plus the gym is much cleaner than most.
Fantastic experience: Alexandra(Lexi) was my member service representative and did a outstanding job with her great communication on what the company offers. Lexi did follow up the next day which was impressive so I came in and signed up. If you want top service and not pushy I highly recommend contacting her. Very friendly and will walk you around the facility . Very clean facility and tons of equipment. GREAT job Lexi:)*****
Fantastic experience: I love the gym...its a little irritating though when I'm at my own station and when I stop to breathe and drink some water I'm told that i need to wear my mask. Then I watch the staff train someone in a crowded area where a woman 2 feet away worked out and during the break had her mask down the entire time and the staff said nothing. I'm also a grown man, if my mask is down other adults should know it's probably for a good reason...like oxygen and water. After that my mask was right back on.
Fantastic experience: I love the kids care here! My son is not fond of anyone but me. Surprisingly, he loves sage (I think that’s her name). I feel so much better working out where I know he is in good hands with her, I don’t feel guilty taking my time and instead it’s a great outing for my 11 month old son too! Everyone is friendly and it has a great atmosphere! My family all loves the rock climbing and sauna as well. It’s always so clean and equipment is well-maintained.
Fantastic experience: Mountainside Fitness Surprise has changed my life in the last couple of years. I starting coming to this gym a few months after I had my first baby. As a new mom the childcare staff was so welcoming and reassured me that my new baby would be taken care of. She is now almost two and I think she loves those ladies more than me. The classes here are top notch! I normally hesitate getting a gym membership because I don't have the discipline to workout on my own. The classes are what keeps me coming back, they have a large variety for all skill levels and the instructors here are phenomenal. I am in the best shape of my life after having my first baby and I owe it all to Mountainside Fitness. If you're interested in the classes here I highly recommend Evenstar and Kim K. They are both so motivating and personable. They have taken the time to get to know me and encourage me to come back. I love this gym!
Fantastic experience: I've been a member of Mountainside Fitness for several years. About 3 years ago I decided to take my fitness to a higher level and get with a personal trainer. I had seen Troy Sienkiewicz train other members and thought he would be a good fit. Troy has been amazing. He pushes me to achieve my goals, listens to what I have to say and has a level of customer service that is surpassed by none. I chose Troy 3 years ago to help me achieve my fitness goals and would choose him all over again and would definitely recommend him.
Fantastic experience: I love mountainside Fitness! Troy Sienkiewicz has been my trainer for the past 5 years. In those years I have grown in my wrestling career as a competitive wrestler. I have gained strength and confidence. He is always holding me accountable and pushing me to be the best ME I can be. Every personal training session is new & exciting.
Fantastic experience: I am a member at the Surprise location. I also train with Troy Sienkiewicz. I have had fantastic results with my training, which includes over 40 lbs weight loss so far. Troy holds me accountable, pushes me, educated me & listens to my concerns. I’m happy with my experience and would refer anybody to him who is thinking about starting a self improvement journey. Today (3/23/19) was measurement day and I’m excited to report my new grand total of weight loss is 48 lbs., this gets me past the goal weight initially set. Troy reviews all of my numbers at each measurement and updates my diet plan accordingly every time. He provides ideas for meals/foods so you feel more confident in your ability to continue to improve. I have been given new numbers to strive towards each day, a revised written workout for the days I’m not training with him and more ideas on how to achieve my new goals. All of the tools, support, encouragement and assistance everyone needs when working towards improvement. Best Trainer I’ve ever worked with - if you’re considering signing up with a Trainer ask for Troy!
Fantastic experience: Mountainside Fitness in Surprise is the best! I have been a member for 10 years and have never had a problem with any of the staff. The variety of classes good and the instructors are enthusiastic. I also have had personal training with Troy off and on. Everyone pushes you to your personal best. Completely happy with my experience!
Fantastic experience: I have been a member for the past five years at mountainside fitness. I have had Troy Seinkiewicz as a personal trainer for the past four years. Troy is a wonderful personal trainer who takes the time to hear his clients. He is great at motivating and goes above and beyond. I have and would recommend him as a personal trainer. If you want accountability, someone who will write out workouts for you, review food intake, have you text him your calories everyday if you need the extra accountability.... what can I say he is a supportive trainer that really cares. I really enjoy this gym and the atmosphere of feeling at home.
Fantastic experience: Joined MOUNTAINSIDE about six months ago because my family (wife and two boys 17 and 14) wanted to join a gym with basketball court. They talked to us ,gave a tour and we did family membership. I didn't go for the first two weeks. I used a treadmill but wanted to get more out of my membership as they had a ton of machines I had no clue on how to use. I did a fitness consultation with my wife to find out how out of shape I really was. We agreed to see a Personal trainer for 3 months. The name they gave us was Troy Sienkiewicz, good luck trying to say that. He is the best assets the fitness center has. I signed up for a 30 minutes once a week, and Troy will make you work all 30, and don't be late. We had amazing results, thanks to Troy. After three months I now have my two boys training with him (the 17 and 14 year old want to get stronger but also swell). Troy is always upbeat ,positive, and motivated. You may hate working out buy having Troy as a trainer will make you go back enjoy you membership more. If you want to join a gym, go to Mountainside Fitness and have Troy train you. You won't be sorry.
Fantastic experience: I started training with Troy when I was 12 years old and I just turned 13. He's a great trainer who makes working out fun which makes me want to come to the gym. "I've gotten strong and I have gained confidence. Troy is not only a great trainer that connects with me he also is a great mentor. Plus he's an absolute unit.
Fantastic experience: Mountainside has something for everyone in my family. My son loves the huge childcare, especially the bounce house obstacle course and the basketball court! The staff is so amazing, I have a newborn too and am so pleased with how the team goes above and beyond to take such great care of him. I love that I can watch the childcare tv’s and see what my kids are up to while I get in my workout. This gym has more machines than I’ve ever seen and a ton of space to do functional workouts. Kudos to the staff, they make coming in for my workouts so much fun! I’m always greeted with a smile and they all know be my name, keep up the great work!!
Fantastic experience: This is the best gym in Arizona! Don’t let the other cheap gyms fool you, they don’t come close to Mountainside. The staff is so friendly no matter when I come in for a workout. I’ve never been to a gym that focuses on cleanliness and customer service like the Mountainside Fitness in Surprise! I’m a loyal member no matter what!
Fantastic experience: Love the gym, the classes are great, the equipment is always clean and always the best welcome in the morning. All I have to do is tell my kids we are going to the gym and they get excited to see Jodi at the front desk and all the childcare staff. Shes always happy and towel in hand ready every morning!
Fantastic experience: Compared to other gyms around here, this one is my favorite. Always clean. Staff is always friendly. My friend uses the childcare they offer and loves it. Definitely worth paying a little more for a great gym.
Fantastic experience: I see people complaining about stuff that doesn't make sense to me or my husband who is a independent personal trainer. Compared to EOS, where he worked this gym is a really great place for families to come and get fit. If you want a cross fit environment this definitely isn't it. I'm going to get fit regardless of what is in this gym because I have the desire to do that. The classes are free for the family pack which is a bonus for me because I like Yoga and Pilates. If you want a family oriented gym this is definitely the place to be! I love it!
