Doesn't take much to get that bounce, so be careful speeding up the descent. If you dive bomb it, you'll lose tightness and bury yourself.
A good way to start is to practice with a lightish weight and get tight, drop down normally, then just above parallel release your hip flexors and drop then, but keep abs/core tight. Just that small drop will get you a good bounce.
Chances are if you are going below parallel and getting off the bottom before getting stuck, you actually are getting a bounce, you just maybe don't recognize it or think it maybe should be more pronounced than it actually is.
More quad strength helps getting better off the bottom.
And yes, the answer is more squats! haha.

Hack away at anything which isn't essential. Do what you love, and do it often. Fazc.
Everything competes for recovery so more assistance is not always the best idea. miked96
