I just figured out who the guy is. I'd been wondering for a few weeks.
About 6 or 7 years ago I was at the gym on a Sunday night. This guy had loaded 11 plates on each side of the leg press sled. He was probably 17 or 18 at the time, maybe a little older. He proceeded to do 4 reps of about 4 inches and then racked the weight. He then proceeded to take ALL the plates off one side first...every single one. I was in the corner near there doing some cable work. I knew what was getting ready to happen...
He got to 3 plates left on one side and I thought to myself, "This dude has no clue what's getting ready to happen..." I could have said something but I wanted to watch the disaster unfold.
He takes the 3rd plate off leaving 2 and the machine starts to tip over to the side where all 11 were left. It falls completely over and makes what sounds like a small explosion. The machine bars you slide 45's and such on to were bent all to hell on that side. Knoxville865 just looked at the machine for about 5 seconds, picked up his bag and left.
I never saw him at that gym again. Seen him around a little since then. He's a permabulker...
