for example lets say if u have a athlete who dont squat for 3-4 weeks but he uses this method once he return to heavy squatting its not a big adjustment with getting use to the heavy bar on ur back. hope this makes sense..
I understand what you are saying there, but then its more of an assisted squat, and not an overspeed squat. Here's a video of an overspeed squat from DB Hammer's old site
