I've been watching the Brooks Kubik vids and like them. In his power rack training video, he mentions that he relies on bottom position training as his primary training tool. It really helps with exploding out of the hole. From looking at it, it seems very similar to doing a box squat. In the box squat, you come down, pause, then explode up. The bottom training just takes out the initail coming down part. It also rests the weight on the pins instead of you (the box). So is it pretty much the same thing?
