Lie on a flat bench holding an Olympic barbell with a close overhand grip. Start with your arms fully extended above your chest. Keeping your upper arms fixed, slowly bend your elbows to lower the bar toward your forehead or slightly behind your head in a controlled motion. Pause briefly at the bottom, then extend your elbows to press the bar back up to the starting position. Keep your elbows tucked in and avoid flaring or using momentum.
