How then to prepare for double and triple back? Look at high you are releasing off a set of rings or high bar or vault.
I'm just responding to the closest equivalent to a DL. Standing back when it comes to BW.
Of course, you could start using ankle or vest weights with BW movements but then you are basically using weights, so it makes it moot since we were looking for BW only.
5' depth jumps aren't really that difficult or taxing. It can be more of an issue building something 5' feet high to jump off. It's actually easier to just pullover onto a HB, step on and jump off than build something 7.5 feet tall to jump off, much less that's stable enough to climb and jump off (besides a ladder).
