The only reason why I had to turn it away is because the few things that I like to do with the gym, they do not offer. I would still recommend. The price is a little bit pricier than the competition, and they do charge an extra $25 to use the pool that you also have to make reservations for. They do offer classes and personal trainer services. I didn't get the cost, but I can't imagine it being more than competitors. Thank Brian , good job!!!

After a few classes, I found their HIIT/Cardio intense (at least for me) programs very helpful for my races that require more than just running. At OTF, there's treadmills, rowers and the weight floor. You can choose where you want to start, or let the front desk pick for you. The space is a little smaller than Chelmsford, but it's convenient because I can jump into class right after work. Also, most days run classes until 6:30 unlike the other branch I go to. After attending a month's worth of classes, I can definitely say that their theory works (stay in orange/red zone long enough and you'll continue burning after class). Almost forgot, if you sign up for a class and miss it, there's a $15 fee! That's one way to stay accountable!

I lost almost 2 inches in my belly (that was a big win win) Finally, I'm not only lost the weight in my most concerned areas but as a bonus got so much stronger in shoulder and chest areas. I absolutely will continue to work out with Slava and Anna constantly. They are amazing people who care about your goals and check on you all the time! Below are my images (3 weeks apart)

Why did they put racks of weights in the middle of the stretching area floor where normally it is put on the side , which had space .

The nearest gym to our temporary residence was the Planet Fitness in Waltham and we could not have been more pleased. We want to thank the manager, Chan, and his staff for making us feel welcome and accomodating us for a short period membership. The Planet Fitness offers a full suite of both cardio and strength equipment that addresses all of workout requirements. And there is ample duplication to enable a large number of patrons to burn off excess calories, stress, and energy. This gym is well maintained and the staff was noticeably making rounds to ensure proper functioning and cleanliness. When repairs to equipment were needed it was usually accomplished within 24 hours. The gym hours are great and meshed nicely with our hectic schedule. Weekday hours are from 5:00 am until 10:00 pm which ensured we could get in a daily workout. The patrons here are very friendly and and we enjoyed the social dimensions of being in the gym. We also noted that everyone is meticulous about cleaning the equipment after completing a set. Great facility with a wide variety of equipment and an attentive staff and genial patrons made for an exceptional experience. We want to thank Chan and his team for making Planet Fitness our travel gym in Boston!

So much for their stellar five-star reviews. Psh! Update: The fact that the owner was so quick to call my review 'petty' when he didn't return my calls for months goes to show the line he's ready to walk just for the sake of maintaining a false reputation on yelp. It also speaks volumes of how mindful he is of other's time. We all come from a different place in our respective lives Mr Owner and all I expected was an acknowledgement. P.S: Don't assume people are stupid enough to tell the different between a genuine apology and a snarky comment. I hope have a fabulous day!

Boston Underground Strength Training is a godsend in the sports fitness community. I spoke with…read moreAngel on the phone to discuss my goals, recovering from a multi-year shoulder injury and getting back onto the path to powerlifting, and we set up an in-person consultation. The consultation was quick and thorough and we set up a plan of action to get me back in shape to lift heavy again. It took a while but trusting Angel and the other trainers here was the best thing I have ever done. I want to say it took about 8 months of recovery based training with the semi-private training group but I no longer have the chronic shoulder pain that I first walked in with. Since coming to Boston Underground Strength Training and going through the recovery training I have competed in three powerlifting meets and have been performing better than I could ever imagined thanks to the excellent programming and coaching provided here. Without Boston Underground I would never have been able to recover from my shoulder injury and probably would have had to give up on my favorite hobby. I wish I could rate this higher than 5/5. -Kyle Campofiore

I've lost track of the number of times I've said, "this is the time I'm going to stick with working out." I started going to Fitness Together last year and it's been exactly what I needed. No crowded gyms or waiting for machines. Expert trainers who handle all the thinking (and racking weights!) for me. Sessions on my calendar that keep me accountable. The trainers plan the workouts, track my progress, and actually make sure my form isn't awful. It's amazing how much easier it is to stick to a workout routine when all you have to do is show up and focus on picking heavy things up and putting them down. It's been the only way I've actually stayed consistent. If you've got fitness goals but zero time to waste, definitely check them out. Super glad I found this place.

Chained Evolution has everything that I was looking for food/nutrition, exercise classes, and 1 on 1 training sessions that fit my schedule, an all in one stop shop providing access to all the things that I needed to reach my goals, which made my journey process very convenient. They gave meme the tools for success. Just recently I finished a 5 mile run this year and finally have the confident to wear a bathing suit for the first time in my life! Going to Chained Evolution helps me to enjoy my life more and continue my healthy habits. I am constantly achieving things I never thought possible and I owe it to the Chained Evolution Family!
