When you do Jumping Jacks do your heels touch the ground?
Will you perform an experiment for me? (This is a jumping jack. No fancy workout clothes necessary.)
Go ahead and try it. I’ll wait… Just do a few. 5–10
I noticed that my heels are off the ground the whole time. I am doing it on the balls of my feet and my feet are doing most of the propelling work.
What about you? Are your leg muscles doing most of the jumping?
Have I been doing it wrong?
