How do you know when to progress from alternating bounds to single leg repeats?
well, get them on vid? you really want to see yourself first, but i mean, the form should be there somewhat before you progress.. it's not like you have to spend forever on alternate though, you can always play with single leg bound "progressions" and progress slow with those also, it's a very different movement.
first progression for single leg bound is just a light cycling of the leg as you go forward.
