Bender Ball is an electrical abdominal exerciser. The founder Leslee Bender has designed a complete set of ab sculpting moves for optimal results, which, combined with her Selective Stabilization™ method, delivers the ultimate ab development routine. These exercises work out many muscle groups including the upper and side abs, as well as those hard-to-reach lower abs. The Bender Ball helps to relax the muscles that are trying to avoid training and helps to activate the muscles that are really trying to focus on. In the Bender Ball workouts, one can also choose the intensity and tempo that feels itself comfortable just by changing the leverage of the body. The Bender Method gives far more range of motion to extend and then flex forward. This exerciser offers six modes and ten settings to firm and sculpt multiple muscles.
