I took a rowing class with Jordan, he was fantastic. I could tell he was extremely knowledgeable about fitness, but also about rowing. He was super helpful with technique (rowing is not my forte, but I do enjoy it). Also, given we are in covid, I must mention the gym was clean, Jordan was conciliatory to maintain social distancing when we had our masks off and everyone sanitizes their equipment thoroughly. Thanks so much for the workout SLS! I will definitely be back!! My only business suggestion is to put some signage on the building because you have a phenomenal space I think is being overlooked by some.

Plenty of cardio and weights equipment, all functioning well, with plenty of duplication so you're not waiting for a machine, and a clean facility with music at the right level. The "extras" like towel service, soap and shampoo, and things like pools and saunas aren't included, but it's a "value" gym, and for my $30 monthly fee, I feel like I'm getting a great value. As for ending the membership, they are up front on sign-up that there's a two-year commitment or you pay an additional fee, so I wouldn't expect that to be waived. Finally, a shout-out to Kim at the front desk on weekday mornings, who greets each member by name and exudes positive energy to start the day. She always finds ways to spruce up the club between check-ins and is a great ambassador.

The gym has every piece of top quality equipment you could possibly need for strength training and everything is in great condition.

The owner Paul is extremely friendly and even works out at the gym himself. He provides personal training at the gym and is extremely well informed when it comes to fitness.

The Details: Several years ago I switched from traditional conditioning (machines, rote freeweight exercises) to functional training. If I only knew sooner... The trainer who originally taught me and my kids moved out of reach. Since then I've engaged in a pretty arduous search and ended up at SOS. As far as I can tell, it's one of a handful of gyms of its kind in the Boston area, and it happens to be at 73 Princeton St., North Chelmsford MA 01863 (https://www.skillofstrength.com). SOS does a terrific job of translating cutting edge methods to well structured and original routines that can be followed by all levels of ability. On one hand there's a somewhat more casual crowd that does a modified version of the day's program (I'm in their MOVE class) and they seem quite content. I'm absolutely, 100% all for that. At the same time, there's another crowd that's always pushing for the next level. Despite the wide ranging audience, SOS underscores the experience with some very subtle social norms - very healthy, and it creates a great vibe. My first experience with SOS was sending my high school aged son through their COMPETE program. It accomplished everything I was hoping for - measurable gains in quickness, strength, cardio, reinforcement of footwork, increased confidence, and familiarization with a vocabulary that athletes require if they're going to progress. All in a personal, incredibly positive environment. Why SOS works for me: starting in my teens and stretching into my late 30's I spent a good portion of time working with skill coaches and strength & conditioning coaches. Together, they made a huge difference in my progress. I don't play a sport anymore, but I still want a technical workout oriented toward increased fitness. SOS delivers in spades. I'm a bug for technique - I actually believe that 5 pounds done right is better than 50 pounds done wrong. As a result I'm constantly asking questions, getting terrific guidance, and no one's lost patience or interest - instead, they seem to be totally into it. SOS has also taught me additional, helpful routines for balance (which are actually fun, and this stuff is supposed be fun), and I'm still pulling myself together on their footwork drills - happily. If you have kids or student athletes who would benefit from a thoughtful, engaging workout, or if you're looking for something different and well structured, or if you simply burn for a good workout, SOS is a terrific place.

Great place to train, with great instructors. If you are looking for a place where the coaches pay…read moreattention to detail, come to SOS! You will not regreat it! Raphael
