- 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
