Looks great!
One quick clarifying question:
When you "hit the wall" my understanding is that it is optimal for that back heel to stay down. ("stretch")
Is that correct?
But with the greater separation (front/back direction) of the feet in this drill,
does that make it more difficult to keep that back heel down, I wonder?
Corlay, I believe it is during the 2-step drill that you want the stride foot heel to touch the ground.
