guys, i read an article a few days ago in a magazine, there was a doctor who claimed that banging plates (45's) or any weight for that matter on bars can be more dangerous than you think....his theory was this, that the sound, the high-pitch that the plates make, send some type of sound or shock to your muscles, causing them to "rest" quicker....after a workout, the fast-twitch muscles will become idle according to him, if you bang the weights too hard, and if you pay close attention, ecspecially after a chest routine, he claims you can see your chest twitching do to the sound of the plates smashing together....i think its bogus, just curious if anyone ever heard or read the same article....Adieu
