Not All Deadlifts Are Created Equal

There was a recent post about the movements in Crossfit and how almost all of them, sans thruster, come from other schools of training.  A caveat to that discussion is how the deadlift or for that matter, any other traditional power or olympic lift, is used in a Crossfit metcon.  When we lift for strength, in the deadlift for example, we do not touch and go or rebound.  The reasons could be for another post but essentially if you get good at rebounding you skip an integral part of the lift.  A good analogy here is comparing the kipping pull up.  If you always kip, you leap-frog a very important part of the movement, the initial change of inertia at the bottom. 
Anywho, todays deadlift was heavy, but it was not about a powerlifting perspective.  It was about, in a healthy position, getting the bar from point A to point B as fast as possible.  The example of this is the amount of knee flexion in the bottom of the lift.  In a classic deadlift set up you want to find good tension for force production in the posterior chain by limiting the amount of knee flexion.  But when you're talking about rebounding, as some folks noticed today, there is an extra benefit to letting the knees bend a little more at the bottom.  If you can time this knee flexion with the rebound of the plates, you'll find the bar firing back up.  Here is Mark today hammering through some deadlifts with a little more knee flexion than we'd probably see him with in a classic deadlift strength workout.
