Arm Trainer Home Machine - Chest Expander

Build chest and arm strength at home in just minutes a day

This arm trainer gives you a full upper-body workout without a bench or a rack of weights. Grip the padded U-shaped ends, press them toward each other and control the bar as it pushes back to work your chest, arms and shoulders. It comes apart for storage, so it fits in a closet, drawer or gym bag.
