Pure Fitness-STL, St Louis

As a mother, certified personal trainer, and owner of more than one business, Kelly Sommer doesn't the buy the "I'm too busy to exercise" excuse. Nevertheless, she makes it easy for her clients at PureFitness-STL to schedule a group class or private session, fitting workouts into morning and lunchtime slots. Her boot camps cater to visitors of all backgrounds with modifiable moves and a nonjudgmental vibe, which stresses the value of teamwork, partner drills, and squats that turn into trust falls. Kelly changes the routines daily to activate all of the body's muscles, but refrains from badgering her students. Though she provides the key ingredient of accountability, she insists that her patrons hit health milestones for themselves, not for her.
