Skull Crusher (Digital Resistance)
Also called Digital Resistance Skull Crusher
How to do it
Grip the digital-resistance handles overhead or at the anchor point and lie back with elbows fixed pointing up. Lower the handles toward your forehead by bending the elbows, then extend back up under control.
Setup
Align a bench with the low digital-resistance cables and hold both handles evenly above the shoulders. Keep palms neutral or down, wrists straight, upper arms fixed, and elbows pointed forward.
Where you should feel it
Through both triceps during the extension and loaded return, with the front shoulders holding the upper arms steady. Keep the handles balanced and elbows from drifting.
When to use it
Use for programmable lying triceps volume and controlled eccentric loading. Favor repeatable bilateral sets of 8-15 reps.
