The Bala Pilates Method Straps are Pilates resistance straps that anchor to a door, sturdy railing, heavy table or couch, which turns a clear stretch of floor into a workout space. Two straps with auto-adjusting wraps slide open to fit around a hand, foot or ankle, so there are no handles to hold. The same setup works for Pilates, stretching, strength training, yoga and barre. What Our Gearhead(R) Experts Are Saying:"Medium is where I start, and Heavy is the pick once larger muscle groups like legs and glutes take over. Stepping closer to the anchor makes a movement easier and stepping back makes it harder, so I adjust mid-workout without changing straps."
