Let’s say you’re 5’10-5’11
I used to think that 180 lbs shredded at that weight would be no problem for many.
But I think pretty much almost everyone thinks that their bf is lower than the actual first few years of their lifting career. Everyone thinks that you can cut from 10% bf to 5% by losing like 5 lbs, but in reality, you need to lose way more even if everything (diet, rest, training) is on point, unless you have the help of PED to retain or even gain muscle while cutting.
I would say 170 lbs is a really good contest weight at 5’10-5’11 if you have average frame, 160 if small and closer to 180 lbs if you have big frame.
