I've been thinking and I'm sure I loaded the bar wrong with 230 instead of 220.
I remember checking it because it didn't look right but my mind was on the lift so still got it wrong.
Thinking back the bar had each side red, yellow, blue yellow, red, white which is 25, 15, 20, 15, 25, 5.
So no wonder it felt so heavy so glad I made it would of been really pissed if I failed because of loading the bar wrong
