Thanks for the input guys, i think i gotta better idea of what's going on, but I guess i should've chosen my words more carefully in my first post. I didn't literally mean i was letting the bar rebound off my chest cavity, i just meant i was letting it come in contact w/ my chest, then exploding the weight upward. i think "bounce" was painting a wrong mental image, sorry for the confusion. what i was doing looks pretty much like the gif that Whitelightning posted (except w/ a lot of those 45's missing!). Thanks for the tips,
