Well I recover kinda bad after KB swings but I'll keep doing them until my body eventually adapts to them in some way.
In terms of bounding, bilateral bounds, of any kind, are impossible at the moment because the amortization phase is incredibly long. It's like when you put a good standing vertical jump guy to do consecutive maximal (or even submaximal) jumps - he will suck very hard at them. I don't load at all on any of them. It's basically a jump, a crash, a reset and then repeat.
And then I can't do single leg bounding on my right leg. So as you can see, things are pretty messed up. My idea is to keep on doing sprints first, then do limited bounding. And by limited I mean say 3 bounds. And focus on these 3 to do them quick and powerful and all that. When I can do them well I increase to four and so on. Also it might be a good idea to do some sort of tuck jumps of jumps on spot (say jumps at the rim) for a while until I can at least take in SOME energy before and after each subsequent jump.
It still doesn't make any sense whatsoever why is the bilateral jump, of any kind, so unnatural. I guess because people (me) walk unilaterally, they don't hop on the streets on two feet. A one-leg jump is simple because it's just an exaggerated natural movement, an exaggerated "step". To me, at least.
