About SLS

Sherri Laffey Sarroufs lifelong dream of offering a holistic fitness/strength and conditioning center came to fruition when SLS Fitness opened its doors in January 2010 in Lowell, MA.  Sherri wanted to offer individualized attention to all members. After years of watching countless people ‘working out’ not knowing what to do and/or not seeing results Sherri was intent on offering each member something different and unique.

Most workouts at SLS Fitness last only 30 Minutes! That’s it!  Her philosophy was to educate people to move well first and to train the body – not drain the body.  Her holistic approach focusing on healthy whole food nutrition and offering a wide variety of programs started a fitness revolution in the Merrimack Valley. Her goal was to place everything under one roof.From intense workouts and relaxation classes to yoga and meditation, to Pilates and beginner workouts, to boxing, MMA, Olympic lifting, Spartan Race training and strength and conditioning for both individuals of all ages and sports/school teams and groups. SLS has now grown to 3 locations and offers more than 180 classes per week!  SLS has partnered with Lowell General Hospital, Gametime – Jr. Spinners baseball, Rivals baseball, Rock Steady Parkinson’s boxing, Metabolic Effect, and St. Jude Children’s Research Hospital.
