SLS Fitness 345 Chelmsford Street, Lowell, MA 01851

"Nothing but great things to say about SLS Fitness. The culture of this place is what keeps me coming back. I work in sales where my hours are very long and unpredictable and it's often hard for me to go there consistently. Every time my wife goes in without me, she always comes home telling me that the staff was asking about me. It's this kind of personalized attention that you don't get at the big gym franchises. It's not overly crowed and I really enjoy groupy atmosphere. You can tell everyone is there for the same reason and you have unlimited support if you need it. If your looking to take your workouts to the next level, I HIGHLY recommend looking into PT (personal training) with any of their coaches. I've personally seen huge progress since I started it 2 years ago"

"SLS is a business that you can trust! I’ve been going to the gym for about 8 years now, and the management and coaches are amazing and care about their clients. I learned especially during the past two years with the pandemic, that SLS does everything in its power to keep its staff and clients safe and well. I can’t say enough positive things about this gym and encourage anyone interested to check them out."

"Being a member at SLS has changed my whole outlook on fitness and nutrition and even how to breathe to relax the nervous system. The coaches and staff are awesome and well versed in all areas. They are patient and help modify all the moves so that everyone can feel comfortable and be successful. I love to take a weekday class regularly on my lunch hour as I work less than 10 minutes away. I will never take a job that is too far from SLS! Also they have great sauna packages to detoxify and aid in recovery after a workout. There are lots of great instructional events and programs as well as private training sessions that have been beneficial. Love this place!"

"Best gym ever! I have been a member for over 8 years and never want to leave. The trainers, facility, classes, equipment are all fantastic. What really keeps me coming back is the community! I have never been to gym that was such a supportive and fun environment. The trainers get to know you, the other members are friendly, and there is always something going on a fundraiser, a special class, a seminar, etc. It truly makes going to the gym an enjoyable experience!"

"SLS Fitness has so much to offer everyone. Most classes are 30 minutes so I can fit it into my busy schedule. The classes are challenging and the coaches are all great at offering modifications when needed. The members are welcoming and supportive and I never feel intimidated even when I'm in a class of people who are further along on their fitness journey than I am. My personal training sessions with Coach Donny have truly been a game changer. I would suggest SLS to anyone whether you're a beginner or a seasoned athlete."
