WHY THE IRON CRUSH FINGER EXTENSORS ARE SO IMPORTANT
When it comes to hand and finger strength, most people focus almost exclusively on gripping and pinching movements. As important as these movements are, that's only half of what your hands need to be strong and healthy.
The muscles in your hands and fingers are arranged in opposing pairs; flexors that close your hands, and extensors that open them. To maximize performance and minimize your risk of developing unwanted and avoidable hand and finger problems, it's crucial that you exercise both sets of muscles.
Too much emphasis on gripping, and not enough time spent working the opposing muscles, can lead to a host of painful and debilitating problems such as:
Tennis elbow
Golfer's elbow
Tendonitis
Carpal tunnel syndrome
Repetitive strain injuries
Stenographer's finger
Arthritis
Whether you play the guitar, play baseball, climb mountains, play tennis, lift weights, or work at a keyboard, you need to make sure your finger extensors muscles are every bit as strong as your finger flexors.
