Skullcrusher
Lying barbell extensions to the forehead. Builds a massive triceps. It works mainly the triceps.
Flawless ranks it by lifetime volume: Gold, the third of eight ranks, starts at 25,000 kg.
How to do Skullcrusher
- Lie on a flat bench with your head near the end, holding an EZ bar with a narrow overhand grip over your chest, arms straight.
- Lower the bar towards your forehead by bending the elbows, keeping the upper arms still and pointing slightly back.
- Go until the forearms are past vertical and you feel the stretch in the triceps.
- Extend the arms back up along the same path and squeeze at the top; the elbows don't flare out.
These are the same steps you see in the exercise guide in the Flawless app.
