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.

  1. 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
  2. 2Keep your upper arms close to your ears and extend back up, squeezing your triceps at the top
  3. 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
