Why do we need extensors?

Hi anatomy lesson part one: flex your hand and curl your fingers maximally- now try to force the fingers open with your other hand-easy wasn't it, now try it again with your wrist straight -right it was impossible-thus the extensors is crutial in delivering grip strenght -most people neglect them but take a look at the ouside part of the forarm close to the elbow -when pinching there is a little muscle bulge there that actually is caracteristic for good climber -extensor carpiradialis- it in combination with the other strong extensors is what you want for good gripping the real trick is to get these muscles "in par" with your flexor muscles. Another muscle that is overstressed in a climber is the "pronator Teres on the inside of your elbow - it resist the spuupinating (palms up) force of the biceps and have ahell of a job doing that- most peopl do chin ups palms up where they are considerably stronger while climber have to pull up palms down (out) so it is important to do biceps training in this position So start working on that balance - best of luck Björn
