At the helm of CrossFit Lawrence is owner Thomas Thatcher. Certified in everything from CrossFit to USA Weightlifting and CPR, he also relies on his experience as a black belt to lead CrossFit classes that are equally eclectic. During those classes, Thatcher and his team of certified instructors guide participants through daily workouts that incorporate varied, functional movements. They get participants flipping giant tractor tires, lifting weights, and throwing medicine balls, all of which use everyday movements and work every muscle group. Their encouraging shouts rattle the walls of the brand-new 6,000-square-foot facility, which brims with a massive bouldering wall and $30,000 worth of CrossFit gear.
