Been ages since i have tried anything close to PR in any of the exercises, today was the closest. Still could have added 5-10% of weight, but is it neccessary? For who? Not for someone who doesn't compete in powerlifting or any other sport, where maximal strength output matters. Risk just outweights the benefits. It's sad to see people "ego lifting" so often, for who? Why? As i mentioned, it's fine, if it has purpose or at least the technique is in check, but quarter squatting 200kg and risking a huge injury that will follow you for rest of the life just to impress your friends? Decision is yours. Stay healthy!
