There were 3 teenagers on the bench the other day. I didn't pay much attention until I noticed the "big" one (chubby kid) put 225 on it and then, no joke, it looked like he was not just DROPPING the weight on his chest, but actually pulling it down, it fell on his chest so fast!
He then strained with his butt way off the bench to get it up, then dropped on his chest again! He did this 4 times! I thought for SURE he was going to fracture his sternum. His buddies then got on the bench and did this same thing, only their "spotter" had to pull it off of them. However, this didn't stop them from each doing 4 "reps" this way. I had to move to another area of the gym so I couldn't see them.
