Failure is part of it. Fail three times and the weight drops. It is annoying the first few times - usually annoys me because of the amount of effort with a fail at the end.
Oddest bit is any fails I have had, I have blasted past the original failure weight.
5x5 is doing well but I've hit my first plateau on OHP. My lower body is a lot stronger than my puny arms...
Also had a complete dickhead next to me today. Insisted on dropping everything.
Deadlift? Drop the weights.
Take the weights off the holders? Drop them on the floor.
Move a bench over? Oh, he'll drop that too.
Prick.
I would have called him out but he was bigger than me...
