Definition
Form is how you execute a lift — bar path, joint angles, bracing, and rep tempo. Good form maximizes load on the target muscle, distributes stress safely across joints, and stays consistent rep after rep. Bad form leaks force, shifts work to the wrong muscles, and is the leading cause of gym injury.
Real questions
Should I sacrifice form to lift heavier?
No. Weight you can't control isn't training the target muscle — it's training compensators and accumulating wear. Slow down, drop the load, fix the rep.
