Forearm Extensors

extensors -- 2016

Pictured above are the extensor muscles in the forearm. They pull your hand or fingers toward the backside of your forearm. Issues like tennis elbow and carpal tunnel syndrome respond well when you reduce excess tension in these muscles. Remember to work above and below the elbow joint to get your best results. 

The muscles are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others.

The following muscles attach across the elbow joint, to the upper arm (humerus) & the arm (radius or ulna), or to the arm & the wrist/hand (one or more of the numerous bones in the wrist & hand). Click the appropriate link for your interest. (any inactive links will be live soon)
