I was doing deadlifts for like a year and my lower back was always sore the next day. A friend who used to compete just watched me one set and said bro you're hinging at your back not your hips. I spent the next 3 months in my garage filming myself with a phone propped on a toolbox. Still have to think about it every rep but my back pain is gone. Has anyone else had a small form tweak that took forever to fix?
I was at the Planet Fitness on 3rd street doing bicep curls when my forearms gave out before my biceps even felt tired. Turned out I was squeezing the handle like it owed me money for the whole set. Eased up my grip on the next round and suddenly I could actually feel the curl in my arm. Has anyone else found themselves white-knuckling weights without realizing it?
