I just got done a farily short/intense lifting session. While I was in the weight room, a weight room friend, who I see all the time, was lifting. We were both doing chest/tri's. He would do a pyramid up to a heavy weight, doing 5 sets and then trying to max. He did this with Flat, Incline, then he moved to decline. He did 8 sets on decline, then attempted 110% of his max, which he got. He got it up half way, then stopped then sort of forced it up, in a jerk-like motion. The guy was indefatigable.
