This is a 100% positive review of Skill of Strength (SOS). I’m a masters athlete at the local, regional, national, and world level. My needs and expectations are not typical - I don’t go to the gym because I want to lose a few pounds, I go because it helps me compete. I have specific goals and SOS provides the kind of expert performance coaching that I need in order to thrive. Mike Perry and his team understand my goals and mentality and as a result I’m incredibly well prepared. I remain injury free with little or no pain, my physical capacity seems to keep increasing, and I can perform at a level that most people… can't. I’ve been an SOS member for years and I joined after a thorough search of the Boston area for a high performance, technically oriented gym staffed by expert coaches who are on the cutting edge of their field. If you have specific competitive goals and want coaches who work with high performance amateur and professional athletes, all packaged in a gym where standing on the gas is encouraged, you’ll be right at home at SOS.

I wasn’t quite sure what to expect when I walked into Skill of Strength. All I knew was that I was coming off a long period of a few illnesses which saw my body pretty much decimated. At one point I was in a wheelchair and needed help to do basically anything. After about 18 months of PT and continued treatments, I was ready for the next step. I needed to start trying to build back some of my strength and flexibility to make life easier, but I wasn’t sure where to start. My friend strongly suggested checking out SOS and I knew from my first evaluation with Mike that this was the place that could help me. I started with personal training sessions with my trainer, Matt. He has and continues to develop an individualized plan that works on all the areas I need. In just a few months I’ve made big strides. I’m able to move around better and I can tell I’m getting stronger. I’m now to the point where I’m to do open gym times as well as book times under the SUCCEED program. I can’t state enough how much the team at SOS has helped me progress so far and I know this is just the beginning.

SoS is a very unusual gym. They have a goal of being the best gym for your clients is how I have experienced it. Lots of my (formerly) chronic problems have been solved over the 4 years I have been working with my trainer. All of the trainers knowledgeable and helpful, but I think the best feature (and, perhaps, the magic of SoS) is the vibe of the place. This includes the trainers and all the people working out there. Everyone is cheerfully working hard. That's unusual, and much appreciated.

Skill of Strength is such a great place to get fit and feel strong again . I’m 67 years old and I wasn’t sure how I would do. This place is not like any other gym. You see people of all ages and strength capabilities. I’ve been at skill of strength for 3 months. I’ve improved my balance my posture and I just feel so much stronger. I have to say I owe all this success to my trainer Sam. She is so knowledgeable and knows how to get me to push myself.I couldn’t ask for a better trainer. I leave my session feeling so good! THIS PLACE IS AWESOME!!!! My trainer Sam is AWESOME!👏🏻👏🏻👏🏻👏🏻👏🏻

I have been a member for three months now, and it has made a huge difference in my health. I knew I had lost strength during the pandemic, but I had no idea how much I had lost and how poor my balance was. The coaches have been great at helping me modify exercises so I can make progress without injury. They are really good at helping regular middle aged folks gain strength even with wonky shoulders, knees, hips. I am making steady progress, and am confident that if I keep being consistent that I will get stronger.
