The GoldBee BEBOOTY 3PACK MANDALA is a set of 3 resistance bands with a Mandala pattern. The set includes S, M, and L sizes, i.e. all resistance levels. A rubber resistance band is a handy fitness tool for effective exercise of thigh and arm muscles. Even tough the exercises might look simple, they will kick your butt. All you have to do is thread your arms or legs and use the resistance to make squats or donkey kicks more difficult. The anti-slip rubber grippers allow the band to stay in place during a workout.
