I dont mean to make a repost, but I was reading a few previous posts on bouncing squats and I didnt want to bump posts from 2006 back up to the top for no reason. I am also not sure if the question is 100% the same as the old threads also.
I am doing SS for overall size and strength. When I squat I start the movement with my hips moving back keeping my head parallel to the wall and my chest up. At the bottom, without compromising my back being arched, I try to pull my knees to my shoulders and then right at the bottom I, with no stop, move the weight back up as quickly as my toothpick legs can muster. Sometimes it feels like I bounce a bit, and a couple times my knees have cracked (like knuckles) but never painful and they do that when I sit on my feet/kneel (not sure what you call that) or when I get down like a catcher when throwing.
My question is, what is the difference between bouncing the squat, and taking advantage of the stretch from your posterior chain muscles (not sure if this is the correct group that stretches either as squat and deadlift anatomy is a bit messy for me at times with flexors and adductors and extensors and whatever else you want to throw in there) at the bottom of the lift?
Also, is this bad for my knees?
I am not dive bombing out of control. Hips back, down under control, pull knees up, push out of bottom.
Thanks for your time and effort. Again sorry about this being a potential repost.
