You need to dorsiflex when you bound, which you currently don't. That's why you have knee issues (at least if you always bound like you did here). You kept the ankle extended here and landed in plantar flexion which loads the knee up like a bitch. You need to land with the foot more under you than in front of you and that will also allow you to dorsiflex better.

If he's not in shape, then that doesn't bode well for me getting really tired after half a mile.

Do you intend to go up again in bodyweight and improve your strength even more? More bodyweight is not that bad for SVJ purposes.

Heck, everything is great, not just that.

I really like what he said with one-leg jumping, that "isometric-explosive" part. Nobody ever talks about that and I've said that first I think about 9 years ago, that the one-leg jump is more isometric in nature (keeping the leg rigid).

I should write again and say "he's still at 60% bodyfat, he needs to lose some" and see what he responds. If he says I'm right again, then he's not at 20%

 

He said it himself that he's at ~20%

Don't ever do this again. And focus on lowering your bodyfat and nothing else.

You should forget about all this ^^^ and focus on reducing bodyfat. You're both wasting your time and destroying your body/joints jumping at that bodyfat %.
