Difference between foot placements

There seems to be two foot placements when doing certain exercises: on the toes and on the dorsal.

What's the difference between these two placements? Must I be on the dorsal when doing Scap Shrugs, pushups, etc.? Or do I have a choice?

Hi Ali,

The foot placement should follow the course videos. Scrap shrugs and push-ups are on the toes, pseudo planche push-ups are on the top of the foot. When in doubt double check the course videos and pictures.
