Nice vid JackB1!! Your headed in the right direction. My advice would be to start on the simple things. Don't overload yourself. Trust me, if you do you'll get overwhelmed and discouraged. 1st- try looking up YouTube vids about the backscratch position. You can get more zip on the ball. 2nd- bend your knees. Power and consistency occurs when you get the legs involved. Start on those two things and I guarantee you will see a difference..
I don't scratch my head unless it itches and I don't dance unless I hear some music.
