In the latero-medial direction, the supinator (Fig. 2), abductor longus, extensor pollicis brevis and extensor pollicis longus and extensor indices are evidenced (Fig. 1, Fig. 3) [1], [2], [3], [4]. The supinator muscle arises from the epicondyle, the radial collateral ligament of ...
Works the often-undertrained wrist extensors Easy to add to your current arm workout Barbell Reverse Wrist Curls 3. Hammer curls This exercise is often thought of as abiceps exercise, but it’s good for your forearms too. It targets the brachioradialis, which is the largest of the forea...
From these values, physiologic cross-sectional area and fiber length/muscle length ratio were calculated. The individual digital extensor muscles were found to be relatively similar in architectural structure. Similarly, the deep and superficial digital flexors were very similar architecturally, with the...
These exercises require a solid grip to handle heavier weights, which, in turn, leads to more significant gains in overall strength and muscle mass. Moreover, forearm strength can improve your endurance in sports and activities that involve holding or throwing, such as basketball, baseball, and ...
