boxing- you got any tips for using the floor to ceiling ball? its hard!?

Answer 1

Use short and light punches to maintain control of the bag. Hard hits will get the bag swinging wildly that you won't be able to control it. And just like the speed bag, don't take your eyes off the bag.

Answer 2

this exercise is really for hand-to-eye coordination. start slow at first until you think that you can go fast.
