Chick Fitness Gym, Port St. Lucie

A workout routine is vulnerable to falling into just that—a routine. But with her women’s-only outdoor boot camps, coach Allison Reynolds stomps out the flickering embers of boredom, leading groups of ladies through intense, total-body sessions that, like siblings, are never identical. Sometimes, Allison sets classes amid the breezy shores of a lake; other times, students scale the ramps of a parking garage. No matter the locale, Allison’s workouts typically feature heavy doses of sprints, calisthenics, stairs, and a medley of other conditioning exercises.
