Gary's Half-Hour Deadlift Challenge
From this article by Dan John and Chris Shugart:
The second challenge comes by way of my brother, Gary: Load the bar to 315 pounds. In the next half-hour, deadlift it as many times as you can.
Gary, a 61 year-old thrower, did 60 reps during his last attempt. He does doubles on the minute. I suggested that to insure less soreness (as if this were possible) do one rep every thirty seconds and drop the bar at the "top" lockout position on every deadlift.
That's right, drop every deadlift. You'll experience far less soreness this way.
I think it goes without saying to keep good posture here. The upside of challenges like this is that your technique actually improves over the workout and your capacity to work increases.
Now, if you can't deadlift 315, well, maybe that's the problem you're having right there!

Pain is your companion, don't go hide from it."
