I'm sure some of you heard the story about the 150lb Russian guy who deadlifted 700lbs. He would dig a hole in the ground, stand in it (decreasing the ROM of the lift), and deadlift a weight higher than his current max. Over time he would add dirt to the hole increasing his range of motion until he got to ground level.
Has anyone ever tried this? I know it is totally different from the usual PL programs but it kinda makes sense.
