I had a class with Jenn. H. The workout was fine the weight section was definitely too easy with…read moreonly two exercises, and she had a bossy attitude, even bumping up someone's treadmill. I would give it three starts for that but this is why I'm giving it a 1. 1. I booked the class on mind body it said "pass available" During the middle of class Jenn was passed a note and told me to see the desk after class. Apparently my passes were expired but the app and the two studios still let me sign up without a problem, showing that I still had classes left to use! 2. The front desk woman was very nice as we walked through the steps that could have went wrong. She asked me for my credit card, I declined saying"I wouldn't have come if I didn't think I had a class available" seeing these classes are about $28 for a drop in. She understood and she said she would figure it out with the other studio tomorrow morning. 3. Morning comes and I get a call from the coach Jenn. She immediately asks me for my credit card info after I already informed her of the conversation stated above. She proceeds to tell me if I don't give her the card into she will just get it from the other studio I have been to. At that point I had to state very clearly and strongly I do not approve or condone her taking my credit card information . She then CONTINUES to say that someone has to pay for the visit. I tell her I understand but that will not be me seeing it was either due to; the app, her studio or the other studio. 4. I am also in the business of fitness and I have NEVER once seen this kind of pushy-ness or poor customer service. Believe me this has happened to me being the coach and I chalk it up because I want a happy customer and I fix the problem so the malfunction doesn't happen again. Truly haven't see this poor of customer service in years. Yikes!!!

Highly recommend.. All the trainers are excellent and the vibe is great. The playlists that the…read moretrainers play are awesome. The cardio and power exercises can be intense but you need to know your body and know when to tone jt down a bit. Since its a dedicated class with everyone doing the same workout based on instructions and motivation from the trainer sometimes pushing yourself that much extra can be tricky and you will need to know at what point you can push yourself and at what point you need to take a step back and slow things a little. I personally in my first class almost got nauseous because to match up to everyone around me I pushed myself beyond what my body could handle.. Was not the brightest idea.. If you are someone who is thinking about it, I recommend signing up for a class to see if it works for you. You have 1 free class to try it out which you can call in to sign up or even sign up online and if you like it then you can look at their various plans and see the right fit..

It's a no-frills environment - there's a TV in the cardio area but that's about it - but everything is clean and in good shape.

The equipment is in good shape, and they have lifting platforms and bumper plates! I would be a member here if I lived in the area.

F45 is a total-body workout with a mix of cardio and strength. It is interval training so you will never get bored. There are ropes, kettle bells, box jumps, rowing, cycling, and so much more! They are currently running a promotion for $1 for one week trial and totally worth checking out. I signed up for the Founders Rate. I haven't gone to the gym in three years. The trainers will help you if you need any modifications to you workout. I look forward to the results I'll see as I continue on with these workouts.

I have never been to a gym where I look forward to coming back the next day. I started with the…read morefree week and only missed one day. From the outside, it can be a bit intimidating since it's all dark. But when you walk in, you realize that the all black aesthetic makes it look very classy and clean. On the right hand side, the wall says, "Culture Builds Community;" but it's not just a belief. The couple who runs the business, Pam and Jason, are very intentional in bringing the belief to life. In my first week there, I felt very welcome, and part of the group. They do a good job of creating tough, but fun workouts that work the entire body. I am someone who likes working out with others to feel motivated, and I am also someone who is most productive when I am not doing the same thing for too long. Each class follows the same structure where there are about 6-8 stations, each lasting about 5 minutes each. Each workout is very different, and there is always great music playing in the background. Before starting, they go through each workout and during the class, go around and make any corrections in your form which is very helpful in avoiding injuries / maximizing gain. There is a bathroom, but sadly no bubbler (or water fountain if you aren't a Rhode Islander). But, to make up for it, they do have a dog that roams around the gym. She is the cutest, but I am envious of her when she is relaxing while we're all sweating. Currently, their unlimited pass is $125/mo., 10 classes is $165, or single drop-in classes are $20 each. From what I have observed, they do offer personal training, but it might be more expensive. I would highly recommend giving them a try

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
