Constructed of an aircraft-grade aluminum alloy and commercially engineered to stand up to the toughest workouts, the MegaPex Elite™ is commercial-quality equipment that will hold up to a lifetime of training at home or in the gym. The smooth, swiveling action--- courtesy of a ball-bearing design commonly found in heavy-duty, multi-ton machinery---activates more muscles with each repetition and actively reduces strain on wrist and elbow joints. The ergonomically sculpted aluminum handles, gleaming, hand- polished finish and smooth rubber base can take whatever you or the members of your gym can dish out.
