Yea powercleans? come on guys lets get a little more serious around here!
haha, yea i am not a scientist but I DO know that powercleans helped my deadlifts seem "lighter". I should have rephrased that. So with that said, I really did feel like when I picked heavier weight off the floor with the deadlift the weight seemed lighter in my hands than before.
All the other ideas are awesome as well.
