We've all seen them: the gym-goer swinging their whole body to curl a massive dumbbell. This is called ego lifting, and it's the fastest ticket to an injury. When you use momentum or cheat your form to lift heavier weight, you take the tension off the target muscle and place it directly on your joints and tendons. Instead, focus on the 'Mind-Muscle Connection'. Drop the weight by 20%, slow down your repetitions, and actively think about squeezing the target muscle. You will actually build more muscle with lighter weights and perfect form than you ever will by throwing heavy weights around dangerously. Leave your ego at the door.
