What members say again and again
“The classes are well structured and have great range from beginners to professionals with modifications if necessary.”
“Rather than going to a gym and staring at a screen on a piece of equipment, you’ll engage with other people, get a great workout, learn, and enjoy being there.”
“I didn’t expect that given my inexperience, but other members are always friendly, and the coaches have been amazing at meeting me where I am.”
“I already feel stronger and more confident, and I am more aware of how to move my body safely both while working out and when doing day-to-day activities.”
From the reviews
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 was a complete gym phobic before joining SLS FITNESS. From day one, welcomed and shown around I felt the sense of community that’s a driving value here. I was a complete beginner, and was made immediately comfortable with the intake process, and in subsequent classes.
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.
⭐️⭐️⭐️⭐️⭐️ SLS Fitness in Lowell isn’t just a gym—it’s a sanctuary, a community, and a place where transformation feels possible again. I first started going when it opened, but had to step away when my mother got sick. I started back up in April, and I have felt absolutely incredible ever since.
Your first barre class at SLS Fitness
New to barre? Almost everyone is their first time, and a good studio expects beginners to walk in the door. Here's what to know. What to expect: barre blends small isometric holds and tiny pulses at a ballet barre with light weights and mat work — it's low-impact and joint-friendly, but it works muscles you didn't know you had, so a little shaking in your legs is the point, not a problem. Rest whenever you need to; no one will bat an eye. What to wear: fitted leggings and a top you can move in — nothing baggy, so the instructor can see your form. Grip socks: most barre studios require grip socks — bring a pair or check whether they sell them at the front desk; the grippy soles keep you steady during the pulses. What to bring: water and a small towel. Arrive 10–15 minutes early to sign in and meet your instructor. It clicks fast — most people say their third class feels completely different from their first.
