I need to understand if there're differences between these variations: foot pointed on the ground , foot flexed to the ceiling and foot pointed while only the heel touches the ground.
Is it beneficial to train all 3 variations? And in order to move to the next PE, should the 3rd variation,which is demonstrated on the course video, be mastered? Or am I free to train the 2nd variation, which I'm used to and feel more comfortable with?
Thanks!
