PowerFingers rings are an essential addition to any climber dedicated to finger and forearm training. By providing resistance to the antagonist 'opening' movement of the hand and fingers, the rings help balance the stronger flexor muscles by developing the extensors. This helps prevent injury, and can aid in recovery for common climbing complaints such as elbow tendonitis and tendonosis. At the very least they help pass the time on tedious bus journeys.
Five rings of varied resistance - can be combined for fine-tuning.
Naturally, it is advisable not to use Powerfingers if they cause pain, and to seek medical advice for serious injuries.
