I had a clip fall of a bar before and almost dumped 3 plates off one side.
I had a dip belt break and threw out my shoulder because the drop in weight was so drastic that I almost whipped myself off the bars.
Couple weeks ago I was doing suspended good mornings and had a clip on my suspension strap break and had to dump 225 off my left shoulder, thank god the right side held.
While doing blast strap push up I had a handle slip out of the clip and busted my face on the floor.
And finally while doing assisted pullups with a band a couple weeks ago I was on my like 50th rep or something when the lost position from under my feet and went up between my legs and I all my weight was resting on the band which was right on my cash and prizes.
I watched someone else doing presses on a boso ball and the ball popped, the guy didn't get hurt so it was hilarious.
