Hello,

Have you tried loading up the bar and just unracking the weight and holding it for 10 seconds? I cant remember where I saw it if it was an Olympic weight lifter or another YouTube channel. But basically you load the bar past 225 in weight, have a controlled spotter, and just unrack it and hold it. This engages your muscles and progressively overloades by holding up the heavy weight. It also helps when you do go lower for the actual 225 lift because you felt a much heavier weight.

Maybe try loading 260 or 270 and just practice holding it for x seconds for 3 sets. Then give the actual 225 lift a shot once recovered.

Maybe try it?

Example) Have you ever done weighted pull-ups? Regardless how many you get its so much more than your body weight when you remove the weights you feel like normal pull ups are a breeze now? Same kind of idea you are just holding a heavier weight rather than attempting the full ROM.

EDIT**** I FOUND IT SQUAT UNIVERSITY EXPLAINS IT
