One-leg deadlift?

Yes, that is correct. The one-leg deadlift. Some of you experienced this fun last week. Others will enjoy this wonderful movement sometime in the near future. We have done plenty of deadlifting in our workouts, so you may ask, why the one-leg deadlift?

The answer is simple: The one-leg deadlift is designed to strengthen the glutes and hamstring musculature AND train body-righting reflex actions and improve balance. Additional hip and ankle stabilizers of the stationary leg are also highly challenged with this exercise, along with the entire chain of spinal extensor muscles. This is an advanced movement that targets the entire deep longitudinal subsystem.

Or in Dave's words - this exercise will help us wake up our butt muscles so we can learn how to utilize them when we deadlift. So let's hear it for waking up the behind in our quest to improve our deadlifts!!!! :)

I wonder if the one-leg deadlift was used by this guy during his training?
