⚠️ Most common mistake: Letting the upper arms drift back toward your face, which turns the lift into a pullover. Flaring the elbows out wide, which loads the shoulders instead of isolating the triceps. Dropping the dumbbells down too fast and bouncing out of the bottom, which risks the elbows and forehead. Stopping the lockout short and skipping the squeeze at the top, where the triceps fully shorten.

💪 Where you should feel it: Mainly in the Triceps.
