I'll need to have a conversation with them about this, as it's clearly a safety issue. You don't want 150kg dropping onto your back if/when you fail a squat. Luckily I was not under the bar when it kaboommed onto the floor. I was testing the setup as I felt it wasn't entirely safe - and howdy-do it wasn't.
Also of note: I've got a new lifting buddy!
Ohh. I'm regressing. Need to focus on OHP. Not managing 5x5x60kg isn't ideal. However, I want to have spotter bars at shoulder height to dump on, and it was while doing these I realized the spotter bars are really shoddy.
Was a bit disappointed as the plates are humongous. Couldn't fit more than 140kg onto the barbells. This, as I discovered in the next session turns out to be because I didn't look enough for thinner plates. There are plenty available.
