There are various little rules about timing in competitions. You should have a certain number of minutes for your lift, but there are certain reasons why that can change. The other coaches can use that to their advantage and try to mess around with your warm-up, so you think you’ve got five minutes but all of a sudden you’re on the platform half warmed-up. Or they might move the weights up a bit to intimidate the other lifters, see if they’ll follow it and go up too high. It’s non-stop. Until you see it, you don’t quite realise what goes on.
