How can i make my whip stronger in handball?

whenever i whip in handball, it makes the wall but does not go as fast as i want it to. Do i have to swing faster or switch my style of whipping to make it go faster?|||you CAN listen to the guy on top, but thats obvious, maybe you should try to hit it down as soon as you raise it up so it ripples the ball and makes a slicker, quicker, movement. try a few different types of styles to fit and use the one that fits you the best|||this chick I know, waits for the ball and then as if it's all played out slow- mo, she swings it and everything seems to be in regualr mode again. She just swings wickedly fast in an 90 degree angle|||i suggest you come out from the side and hit with the hell of your palm...that should make it go faster...that what i do|||hold your hand in "C" position basically into a cup shape. when the ball enter your palm swing your hand down real quick.|||be stronger YEAH HANDBALL|||Just swing your arm a LOT harder than usual.
