How about dead lifting when a strap breaks. The first thud was barbell hitting the ground - the second thud was me landing on my back after being air borne. Those that actually saw it thought it was fucking hilarious. My view was, ummm, somewhat different.

You're no lifter/gym-rat/bodybuilder untill you do this

God one time I was doing some forearm work with a barbell behind my back doing wrist curls. And this day I was wearing high top shoes with the little metal hook things that you wrap the laces around at the top of the shoe. Finished a set, put the barbell down behind me. Ready for next set. Reach down to grab the bar.... my thumb nail ends up getting snagged on one of the metal hooks. I don't notice, so I pick up the barbell and..... RIP.... Thumb nail successfully removed. Fucking painful blood spurting mess.

Many Moons ago when I started lifting I was at a Golds gym. I went to do tricep push downs and did not like the bar that was hanging. So I grabbed another one and hung it on the rack. I then proceeded to bend over , pull the pin out , and Bam the bar came crashing down busting me in the head splitting me wide open.. I guess the bar I chose wasn't weighted properly for that machine. Sine then whenever I remove the pin and bend over underneath a hanging bar I keep my free hand up to stop it in case it drops.. Lessons we learn!

Wearing a bruise on my chin right now from upright barbell rows!

Me i get goin sometimes and forget to clamp the weight down on the bar and next thing u know there's a loud bang and everyone stops and looks at me lol wish I could say I've only done this once

lol, I seem to always stub my toe on a dumbbell or a plate.
