i was wondering how to curl your toes back further to kick with the balls of your feet. when i mea gerri i have to angle it so that i hit with the balls of my feet and even then i still catch my toes sometimes, and when i mawashi gerry i have to hit with the back of my foot because i cant peel my toes back far enough to hit with the ball. i notice that my sensei can curl his toes back past perpendicular with the ceiling and i can barely get them to a 45 degree angle with the floor, how can i be able to curl my toes back further.
