Détail du Produit

The Heavy Roller is a wrist training device that uses an offset loading mechanism. To maintain your grip during a lift you must squeeze the device and flex or extend the wrist against the direction of spin. The high torque generated at relatively low loads targets either your wrist extensor or flexor muscles to improve grip strength without loading the shoulders. An ideal training tool for climbers looking to maximise their grip strength gains.

Use this device over other grip trainers to provide a more direct stimulus to the forearms whilst excluding the upper arms and shoulders. Compared to hangboarding the Heavy Roller distributes loads over the entire hand by putting much less strain on the fingers. This means you can keep training your grip strength off the wall and away from the hangboard.

Wrist training is used in many ways:

• To increase strength in the wrist extensor/flexor muscles and improve stability whilst climbing. This typically decreases the amount of friction required to maintain contact with less positive holds and surfaces.
• To add variety to a training plan and increase options for targeting grip strength.
• Rehabilitation of wrist injuries: targets the affected area with a progressive load. (More convenient than a rack of dumbbells)
• Rehabilitation of golfers/tennis elbow (tendonitis in the elbow), a common issue for climbers.
