Stability balls have become an integral part of everyday workouts after years of being used by therapists and professional trainers alike.  Core stability and training are the backbone to any sport or a healthy body. Working with a stability ball can strengthen abdominals, back muscles, erector spinae, quadriceps, and gluteals, as well as improving proprioception and posture.

Each ball is slightly textured to prevent slippage and has the size logo'd onto it.  Comes with an extra plug set.
