Put a new spin on your lower arm training with the Twist Yo' Wrist: hit everything from your elbows to your fingertips for gains in strength, endurance, and muscle mass. Give it a turn for strong wrists in all directions and a new way to pump up your forearms, training your grip strength at the same time.
The Twist Yo' Wrist trains both your grip and your wrist and forearm, and the movement is radial (thumbs up) and ulnar (pinkies up) deviation—picture opening a jar of peanut butter sideways with one hand on the lid, the other on the bottom of the jar and twisting. It is designed so that you train both concentrically (winding up the cord) and eccentrically (allowing it to unwind under control).
If you don't have forearms like Popeye, give this wrist roller a try and start working those lower limbs, making them an offer they can't refuse: fall off or grow bigger and stronger.
The One Wicked Wrist Roller trains your grip, wrist and forearm in a flexion/extension movement, as when doing wrist curls (regular and reverse). It is designed so that you train both concentrically (winding up the cord) and eccentrically (allowing it to unwind under control).
Pronation/Supination, Radial/Ulnar Deviation
The development of the muscles involved in supination–pronation is important in all sports, as well as for injury prevention. Throwing a baseball, for example, involves pronation (hands palms down), while swinging a baseball bat or golf club involves supination (hands palms up). The IronMind Wrist Reinforcer and Heavy Hammer II Leverage Bar take the wrist through full range-of-motion exercises in all directions to develop your wrists and forearms into one very strong and very solid unit. Lever, do hold-outs for time, try circles and figure-eights.
