Women’s elbows ‘bend’ more than men’s putting women at a disadvantage?
Women tend to be more flexible, often resulting in hyper-extension of joints. This would not put them at a disadvantage unless a man had a marked limitation of extension. (There is a mechanical advantage as a joint approaches mid-range of its possible movement.
"Many women will be unable to do them - not because of a lack of upper body strength, but because of the carrying angle at the elbow. a man's elbow is typically much more straight than a woman's; this gives them a bio-mechanical advantage with certain activities, such as the pull-up."
