Deadlifts Deweighted vs. Bounced

[Sub-Zero]

I appreciate the comment man, but again, I do not agree with this comparison, there is no other movements that is like this. If my back is liftin 1000 pounds, its lifting 1000 pounds, if I do strict I lose focus. And like was said because I'm not going into powerlifting, but bodybuilding, and I believe STRONGLY that I would have a greater chance of injury deweighting and jerking up, then a smooth bounce.

Force = (masss)(acceleration)

9.81m/s times your weight, = the force down.

when its dead, thats the weight your lifting, but when its accelrating down, it hits the ground and an equal and opposite force propells the weight back up.

the fact is, your not lifting 1,000 pounds when your bouncing it off the ground. its not a guess, its physics

It's not a perfectly inelastic collision, so he's not getting all of benefit of the downward force, but the point stands and is the same one everyone has been making since page 1. Don't waste your time: his ego won't let him take a few pounds off his "deadlift" to do it correctly.

lol lets just work out the physics of it with his weight and tlel him at about what percent of the lift he begins actually doing the full weight

lol, given this,

Well we have rubber plates and rubber matts..

he probably not doing the full weight at any point after the first rep.

It has nothing to do with ego, if it did, I wouldnt be curling 20lbs dumbbells.

But younggash isn't the only one doing 'em w/ a bounce.

I do them with a slight bounce in order to keep constant tension in my back. For BBing purposes, you generally want to try to keep the muscle constantly working.

My guess is that this is like anything else: once you know how to do shit right and have some experience, you can do things differently and you know what you can do and what you can't. Nobody would suggest a newer lifter use the elastic reflex and bounce his deep squats, but olympians do it all the time. Same probably goes for your deads. Unless you know what the fuck you're doing, you probably should stick to deweighting them. I mean, if Ronnie bounces a double w/ 800 off the ground, OK. I still wouldn't tell a guy to do it until he's got some real training experience under his belt.

That said, I'm no BB'r so don't really give a shit whether a bounce keeps max tension on my rhomboids or not.

Good post man, soon I'm retiring from C&C, losing my platinum and moving here, and other places, I hope you guys can stand me!

Doesn't Rippetoe suggest exactly that in Starting Strength?

I predict that youngguns' next trick will be to brag about his 60" vertical set on a trampoline.

please, lets be mature and just chat, not be complete douchebags, because I will talk shit, and it gets messy, lets just keep down k? thanks.

That wasn't an attempt to talk shit, it was another analogy relevant to the topic. I (and a bunch of other posters) keep throwing out these analogies in the hope that you (or others reading the thread) will see the problem with your "as long as X pounds are on the bar, it doesn't matter how it gets from point A to point B" reasoning. Here are another couple that haven't been used: using a bench shirt or a squat suit and knee wraps change the dynamics of the lifts significantly and in a way very similar to touch-and-go deads (by turning it into a lockout since the rebound takes care of the bottom part).
