Grip is the limiting factor. Haha. No kidding, it fails more than anything. Devils said it right. To be able to catch a heavy low catch clean, you have to be a kamikaze. As for the ten count between reps, brilliant idea. The thing that drives me nuts is when I see coaches programming high rep cleans with a bunch of kids who have no technical form to begin. i don’t evr have ANY of my athletes do more than 6 reps. I feel the small intrinsic postural muscle fail to early under load, it increases danger exponentially.
