Cable Incline Skull Crusher
Cable Incline Skull Crusher Exercise Description
The Cable Incline Skull Crusher is an elbow‑extension exercise performed on an incline bench using a cable attachment to emphasize the triceps brachii (long, lateral, and medial heads). The incline setup and cable’s line of pull provide consistent tension through the range of motion while you keep the upper arms relatively fixed. Shoulder and scapular stabilizers help hold humeral position, and a lightly braced trunk maintains a neutral spine on the bench. This variation suits lifters who want a controlled, isolation‑focused triceps movement with clear positioning cues. The goal is simple: move at the elbows, keep the shoulder quiet, and return to full extension without locking hard or using momentum.

How To Do The Cable Incline Skull Crusher Exercise
‘- Set a low pulley with a straight bar or rope. Place an incline bench a short distance in front of the machine, facing away from the stack so the pulley is behind your head when seated.
– Sit and lie back with feet planted and head supported. Maintain a neutral spine and gentle ribcage brace.
– Grasp the attachment with an overhand (bar) or neutral (rope) grip about shoulder‑width. Wrists straight.
– Start with elbows extended above your shoulders and upper arms angled slightly toward the pulley to keep tension. Gently retract and depress the scapulae.
– Keep upper arms still. Bend the elbows to lower the handle toward your forehead or just above the crown, moving only the forearms.
– Stop just before the attachment would contact your head, maintaining neutral wrists and steady shoulder position.
– Extend the elbows to return to the start, finishing with full elbow extension without hyperextending or shrugging.
– Keep elbows close to shoulder width; avoid flaring excessively or letting them drift forward/back.
– Control both directions; avoid arching the low back, pressing off the bench, or using momentum.
– If shoulder movement occurs, reduce the range slightly and re‑focus on fixing the upper arms while the elbows do the work.

‘- Place the incline bench so the pulley sits behind your head when you lie back.

– Grip the bar or rope about shoulder‑width with straight wrists.
– Begin with elbows extended above your shoulders and upper arms angled slightly toward the pulley to keep tension.
– Gently retract and depress your shoulder blades before you start moving.
– Keep your upper arms still and move only at the elbows as you lower the handle toward your forehead or crown.
– Stop just before the attachment would touch your head to maintain control and shoulder position.
– Extend your elbows back to the start, achieving full extension without hyperextending or shrugging.
– Keep your elbows close to shoulder width; avoid letting them flare out or drift forward/back.
– Control both the lowering and lifting phases, avoiding low‑back arching, pressing off the bench, or using momentum.
Cable Incline Skull Crusher Beginner Introduction
The Cable Incline Skull Crusher is a cable‑based arm exercise performed on an incline bench, aimed primarily at the triceps along the back of the upper arms. Because the resistance comes from a cable instead of free weights, tension stays present as the elbows bend and straighten, giving the movement a smooth, consistent feel. The incline position places the arms at an angle where the elbows act as the main hinge, so the triceps take on most of the work while the upper arms stay relatively steady in space.
Muscles around the shoulders and shoulder blades contribute by holding the upper arm position, while a gently engaged mid‑section supports the natural curve of the spine against the bench. The movement pattern centers on controlled elbow action rather than swinging the weight or shifting through the shoulders. Lifters often choose this variation when seeking a more guided, isolation‑style triceps exercise with clear body positioning, steady cable resistance, and an emphasis on smooth, deliberate reps instead of explosive power.
