13 Stripes CrossFit, Harrisburg

A training space of 4,200 square feet. Fifty feet of AstroTurf. Custom squat racks. Pull-up rings. 13 Stripes CrossFit is clearly outfitted for serious workouts. Their trainers lead the gym's namesake CrossFit workouts, slinging an ever-changing routine of high-intensity moves, which participants perform while carrying as much weight as they can. The gym also has its own workout style, Burner X, which matches CrossFit's intensity level but focuses on fat loss; as such, exercisers perform more reps while holding less weight.
