IMPROVED LONG TERM STABILITY - Traditional bicep blasters begin to bend and break due to their weight and use. However, our bicep curvature holder features thick aluminum, strong studs and an adjustable padded nylon belt to give you extra stability for a more efficient workout. INCREASE STRENGTHS AND TECHNICS - Anyone who has taken a bar and works with the curls immediately realises that it is difficult to keep elbows stable. Our curl blaster arm keeps elbows closer to the body to prevent wobbling, forcing the biceps to do all the work. The contoured plate insulates arms and shoulders while holding elbows in a curvature position. Comfort fit: carefully designed with continuous research by fitness experts, customer search and satisfaction pursuit. With thick, padded elbow pads for safety and comfort, super soft foam padding and fully adjustable harness for superior comfort and stability. ATTRACTIVE DESIGN QUALITY - Our Bizep Trainer Insulating Bar has a superior and modern construction with a scratch resistant powder coating. It is a modern and stylish selection of arm blasters for men and women, and relax! Our blasters arms are 100% safe for you and the environment. Non-toxic, lead and PVC free, to avoid unpleasant odours.
