Dumbbell Skullcrusher
Lying with the dumbbells above the chest, bend only at the elbows to lower them beside the head, then extend.

How to do it
Setup
Lying, bells above the chest in a neutral grip, upper arms vertical.
Steps
- Bend only the elbows, bells lowering beside the head.
- Keep the upper arms frozen.
- Extend back to lockout.
Common mistakes
Elbows flaring wide: the bells drift to the shoulders; keep them in. Upper arms rocking: vertical and still. Bells clashing overhead: parallel paths.
Breathing
Inhale lowering, exhale extending.
