A question I answered on Quora: How can someone with small hands dunk a basketball?
Simple answer: Jump Higher.
You don’t need to palm a basketball to dunk it; you just need to be high enough over the rim to throw it down.
I am 6’4” with a 6’8” wingspan. I don’t play anymore but dunked with ease “in my day” — and didn’t not palm the ball, ever, for a dunk.
The below vid is not a demonstration – just showing you how I dunked without palming. Notice how I jumped high enough that both hands were over the rim. With more of a running start, such as in a game, both wrists would be over as well.
Here’s my vertical jump program:
