When people say "repeat until failure", do they mean repeat until you can no longer keep proper form or until you physically are incapable of continuing?
Hello, I'm trying to get back into working out and I often follow workout videos. I always dread doing exercises "until failure" as I've always thought I had to keep going until I physically could no longer do the movement (eg. doing pushups until I can no longer push myself up anymore) though I wonder if that's wrong? I typically fall out of proper form before I reach that point, and I understand that improper form can lead to injury. Am I supposed to just work until I can no longer maintain form? If so, I can do much fewer pushups than I originally thought... thank you all in advance!
