so I like running around and doing some (basic

) parkour, but a problem I've came across is that it tends to hurt my hands when I do certain things. in the simplest case, I tend to climb around on my elementary school playground using only my hands (training for ninja warrior style things

), and my palm skin tends to squish/fold on itself around my fingers. not sure how to explain it. anyways, it makes climbing and grabbing and hanging kind of hard
so, I had some sports gloves and I tried those, but then they simply slipped and I was hanging just by my fingers, and that was worse.
any ideas, any gloves or anything you can suggest for these type of activities?
