He raises the dumbells before he executes his jump.
Which obviously means that the muscles of the shoulder have lifted the weight, not the muscles of the hip or knee. Not only does this make the exercise ineffective for increasing the load, it could even make it easier since the dumbells are moving upward, thus adding momentum to the movement.
And as far as Roy jumping higher, your not basing that on any objective measure. Its not like you play ball with him down at the park and now he is dunking where as he couldnt before.
It could be that he is getting used to the play of NBA basketball and is getting himself in good situations.[/quote]
His form leaves a little to be desired, but he’s getting the results he’s looking for.
Getting used to th NBA game? He’s a former rookie of the year and two time all-star, and he’s only played three seasons. Think he’s got the NBA game down. The facts are he’s had a handful of dunks this season that he wouldn’t have gotten in the past.
He doesn’t get that dunk a year ago. I’m sure he’s doing other things than just loose form weighted box jumps, but whatever he’s doing is working.
