SelFit PowerGrip™ Adjustable Hand Trainer

The SelFit PowerGrip™ Adjustable Hand Trainer uses a variable resistance mechanism to strengthen your grip, wrists, and forearms with each repetition. To begin, simply adjust the grip width and resistance level to suit your hand size and strength. Squeeze the handles together in a controlled motion to activate the flexor and extensor muscles. The resistance increases toward the peak of each rep, maximizing muscle engagement and strength gains. Compact and easy to carry, it's perfect for quick sessions at home, in the office, or while traveling — helping you stay consistent with your grip training anywhere.
