Set an incline bench to about 30–45 degrees and sit back with dumbbells in both hands. Extend your arms overhead so the dumbbells are above your chest, keeping a neutral grip (palms facing each other). Keep your upper arms fixed and close to your head. Slowly bend your elbows to lower the dumbbells behind your head in a controlled arc. Pause briefly at the bottom, feeling a stretch in the triceps. Extend your elbows to bring the dumbbells back to the starting position, maintaining control throughout.
