Durability: They will NEVER break, so you’ll NEVER pay for replacements. Comfort: Fabric is softer against the skin, no digging in, pinching, or pulling hairs. No Rolling – Ever: Our bands have a thick width and inner grip strips. No more frustrating sessions where you’re tugging, holding or pulling your bands. They stay in place during ALL exercises. Every Band Fits: Most brands have a “heavy” band that is too small and an “easy” band that is too loose. Arena Strength bands are all the same size. We vary the resistance of the fabric to change the band strength levels. This means a perfect fit every time and a better workout!
