Robust, Patented Design - Take your resistance training to the next level with the Bodylastics exercise bar. Each workout bar is an ultra-strong, super-thick steel pipe with three connection points. It carries a 300lb rating, withstanding up to 750lbs of resistance. Does Not Strain Your Wrists - Consistent band workouts using subpar straight curl bars may hurt your wrists. Thats why we made our bent curl bar with 45-degree bends! This ergonomic feature allows you to target different muscle groups with various grip angles.
