Barbell Reverse-Grip Skullcrusher
The lying triceps extension with an underhand grip on a straight bar; the palms face you, which keeps the elbows tucked.
How to do it
Setup
Lying on a flat bench, bar held underhand at shoulder width over the chest, arms vertical.
Steps
- Lower the bar toward the forehead by bending the elbows alone.
- Keep the upper arms still and the elbows in.
- Straighten the arms back over the chest.
Common mistakes
Wrists bending back under the underhand grip: straight wrists, a lighter bar. Elbows drifting toward the head: the upper arms stay vertical. Dropping the bar toward the face: slow on the way down, always.
Breathing
Inhale lowering, exhale extending.
