TJ Lawson, Ashley Sell, Zane Roebuck & Mike Sell

Owners

MSP GYM was founded in 2017 with the specific goal of becoming the most client-centric and results-driven gym in the Greater Wheaton Area. Corporate gyms are known for penalizing clients financially for the silliest things, offering impersonal workouts, and putting profit over people. We are different. Our boutique fitness facility combines client-centricity and intelligent programming. We fervently believe that everyone can reach their unique fitness goals, and all of our fitness offerings are organized so that each and every movement can be customized and modified based on training history, age, goals, abilities, etc. We use evidence-based programming principles to help our clients succeed, and we meet with all of our members individually at least every quarter to ensure they’re making progress. At MSP, you are not only joining a gym, but a united community that is here to have fun and support you each and every step of the way. Get ready to join the most goal-driven gym family in the Midwest!
