I've seen them advertised and lots of people talk about using them, but what are the mechanics of using one and how exactly do they help your bench?
Do a search in the powerlifting/olympic lifting forum - they've been discussed a lot...
A child does not learn to squat from the top down. In other words, he does not suddenly make a conscious decision one day to squat. Actually, he is squatting one day and make the conscious decision to stand. Squatting precedes standing in the developmental sequence. This is the way a child's brain learns to use the body as the child develops movement patterns. Therefore, a child is probably crawling, rocks back into a squatting position with the back completely relaxed and the hips completely flexed, and stands when he has enough hip strength. This approach makes a lot of sense and can be applied to relearning the deep squat movement if it is lost. -Gray Cook

If your not a competitive powerlifter dont worry about them... they are worthless and useless to you and a waste of money.
