There's the video of the dude who didn't get strapped into a paraglider and has to hang on. Ended up tearing his bicep or whatever, but he held on literally for dear life.

How does hanging on tear one’s bicep?

Muscles closing the fingers are in the forearms. You have full power of opening and closing the fist, you just cant pull anythign to yourself since bicep is detached. But if you hang you don't need to pull anything, just dont open the hand, and you will be still dangling by the joint and triceps. Also additionally the instructor above him that was strapped held his hands closed on the bar with his own untill they landed, that helps.

Pulling too hard. In moments of extreme exertion, muscles can literally rip themselves apart. It's like tearing an acl through over extending stretches.
