Skull Crusher (Machine)
How to do it
Sit at the machine and grip the handles with elbows pointed forward and fixed in place. Lower the handles toward your forehead by bending only at the elbow, then press back to full extension.
Setup
Adjust the seat, pad, and start position so the elbows align with the machine pivot and remain supported or fixed. Hold both handles evenly with straight wrists and shoulders relaxed.
Where you should feel it
Through both triceps along the supported elbow-extension path, with the front shoulders maintaining upper-arm position. Stop before any forced elbow or shoulder range.
When to use it
Use for stable triceps volume close to fatigue when balance and torso control should not limit the set. Controlled sets of 8-15 reps fit well.
