Skullcrusher
How to do it
- Lie on a flat bench holding an EZ or straight bar over your chest with a narrow overhand grip.
- Move the bar back so it sits over your forehead, arms straight - that slight angle keeps tension on.
- Keeping your upper arms still, bend your elbows and lower the bar toward your forehead.
- Stop just short, then extend back up.
- Elbows stay pointed at the ceiling. If they flare, drop the weight - this one is hard on the joint.
