The wrist roller is a device designed for strengthening the forearm muscles together in a rolling-pulling motion. It consists of a bar of varying lengths, with a cord or rope attached, which the user rolls and unrolls. This is resisted by the weight of a mass at the bottom of the cord.
Another option, is a weight based machine; this type of plate loaded machine will not only strengthen your grip but also your forearm strength. As finger flexor/extensors serve a function as wrist flexor/extensors, doing wrist extension exercises (sometimes called "reverse wrist curls") would also stimulate the finger extensor fibers.
Extensor compartments of wrist (back of hand) The fingers have two long flexors, located on the underside of the forearm. They insert by tendons to the phalanges of the fingers. The deep flexor attaches to the distal phalanx, and the superficial flexor attaches to the middle phalanx. The flexors allow for the actual bending of the fingers.
The second compartment is occupied by the two radial wrist extensors, the extensor carpi radialis longus and the extensor carpi radialis brevis. The third compartment exclusively accommodates the extensor pollicis longus, which hooks around Lister's tubercle of radius and inserts to the thumb. The fourth compartment is the largest of all.
The wrist curl is a weight training exercise for developing the wrist flexor muscles, the muscles in the front of the forearm. [1] It is therefore an isolation exercise. Ideally, it should be done in combination with the "reverse wrist curl" (also called wrist extension) which works out the muscles comprising the back of the forearms, [1] to ensure equal development of the wrist flexor and ...

The extensor carpi radialis longus is a wrist extensor that is innervated by the radial nerve, [2] [3] from spinal roots C6 and C7. [4] All other major extensor muscles in the superficial layer of the posterior compartment (the extensor digitorum , extensor carpi radialis brevis , extensor carpi ulnaris , and extensor digiti minimi ) are ...
Stretching and isometric strengthening are the most common recommended exercises. The muscle is stretched with the elbow straight and the wrist passively flexed. Isometric strengthening can be done by pushing the top of the hand up against the undersurface of a table and holding the wrist straight. [42]
