How to do it
Stand holding a dumbbell or barbell behind your head, elbows bent. Extend arms to lift weight overhead, then lower back down behind head.
- 1Hold the weight overhead with both hands and bend your elbows to lower it behind your head, feeling a stretch through the long head of your triceps
- 2Keep your upper arms close to your ears and extend back up, squeezing your triceps at the top
- 3Engage your core and glutes to keep your torso upright during the movement
Common mistakes
- Don't flare your elbows out or let them drift forward
- Avoid arching your lower back or leaning backward to manage the weight
- Don't use excessive momentum or let the weight drop quickly behind your head
