Hello,
When I try to imitate the athlete in the video by putting my weight around the ball of my foot (he raises his heel by about an inch), my knees are acting up.
When I place my weight on the heel (like when doing heavy squats at the gym) my knees are fine.
I'm referring to the bent leg.
I don't want to work my way up to mastery then learn that I should raise my heel like the athlete!
