Jumps up on to boxes
Are these really of any value?
I'm incorporating jumps into my training from time to time. I've been doing simple jumps from standing to touch a height, resting between reps, and the same thing with a drop of an 18" box. My vert has gone up a couple an inch or two just from all the practice, which is nice.
Does jumping over things or onto things actually provide any effect above and beyond this kind of training besides looking me look fly and beating up my knees?
