They will correct you if your form needs adjustments and will really encourage you throughout the class. I loved the culture where you have a circuit and if you finish earlier than your peers you cheer them on until they finish. I also want to give a special shout out to Coach Laurel who introduced me in the beginning of class to give me a warm welcome. She remembered that I was visiting from Long Beach and was here for the week in Boston and traveling to Vermont. I highly recommend to anyone who is interested in CrossFit. I loved it so much I even bought a t-shirt.

As someone who is an introvert and struggles with confidence (especially in the gym) the coaches go the extra mile to make me feel comfortable and prepared for each workout by providing modifications and words of encouragement! During COVID-19 I have had some of my biggest gains in virtual WODS with the chance to work on skills like pushups and double unders. While I am still transitioning back to the gym in person full time I have attended a few outdoor classes. CityLine continues to prioritize and maintain the health and safety of all their members while putting you through a hard workout and building community at the same time. I look forward to the at home WODS and going in to the gym every chance I get!

However, the drinking fountain upstairs has been out of order for months without any end in sight and now the downstairs fountain is out of order, with little chance that will be repaired sooner. No functional drinking fountain is unforgivable. This is a high traffic gym between Waltham and Cambridge with lots of people stopping off before work and we need water. Photos attached.

I would advise you to avoid peak hours (between 5-7 pm) to be able to use the machines and weights you need. In my experience, it's better to come early at 5:30 am.

I've now been to several CRGs and I like this the best. It's by far the largest. And remarkably clean for a chalk-filled gym. I guess the HVAC system works very well. And one cool feature which I've pictured. A ramp. Go to the bottom and climb up. Side routes are softer, while the overhung routes are much more difficult. I've never seen anything like this in a gym. Very nice. Hoping to come back here again next time I'm in town.

I have been a member here for a few years and would recommend that if you are looking for a gym,…read morelook elsewhere, such as Planet Fitness or Waverly Oaks Athletic Club. This place is affordable for the area, but the fitness area is lacking. They have the basics and some machines, but the area is not maintained, and things often go unfixed for many months at a time. It is clear that the club makes all of its money from the Tennis and Pool centers and caters to those areas. On one occasion, one of the cable machines was broken, and a member took the part home to weld it back together, knowing that management was never going to fix it. On another occasion, the hammstring curl was broken and out of order for more than 8 months. There is a sauna and steamroom in the men's lockerroom that have not been turned back on since the pandemic. Overall, the fitness area is serviceable but dated. The positive is that there is a small group of members, so there is almost always space available. The membership is very nice and welcoming for the most part; there is one unstable person who slams equipment, and management has not held him accountable.

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.

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
