Kettlebell Lying Triceps Extension Skull Crusher
Kettlebell Lying Triceps Extension Skull Crusher Exercise Description
The kettlebell lying triceps extension (skull crusher) is a supine elbow‑extension exercise that targets the triceps brachii, with all three heads contributing as the elbow moves from flexion to full extension. The upper arm stays relatively fixed while the forearm hinges, making this a single‑joint pattern that emphasizes triceps strength and control. A kettlebell’s offset mass increases the stabilization demand at the wrist and elbow, encouraging a firm, neutral grip and steady tempo. Scapular retraction and a neutral spine help create a stable base so the shoulder doesn’t dominate the movement. Use a controlled range of motion to keep tension on the triceps while keeping the kettlebell clear of the head.

How To Do The Kettlebell Lying Triceps Extension Skull Crusher Exercise
‘- Lie supine on a flat bench or the floor; set feet flat, ribs down, and spine neutral.
– Retract and lightly depress the shoulder blades to “pack” the shoulders.
– Hold one kettlebell by the handle in a neutral grip (palm facing in); position the bell over the shoulder with the arm vertical and wrist neutral.
– Set the upper arm about perpendicular to the torso; keep the elbow pointing roughly toward the ceiling.
– Brace lightly; keep the upper arm still as you bend the elbow to lower the kettlebell toward the side of your head.
– Stop just before the bell would contact your head or upper arm; forearm roughly parallels the torso.
– Press back by extending the elbow until the arm is straight without hyperextending; maintain wrist neutrality.
– Keep elbows from flaring excessively; shoulders remain packed throughout.
– Lower and raise under control; avoid using momentum or moving the upper arm.
Kettlebell Lying Triceps Extension Skull Crusher Tips
‘- Lie with feet flat, ribs down, and spine neutral to create a stable base.
– Retract and lightly depress your shoulder blades to keep the shoulders “packed.”
– Use a firm, neutral grip with a straight wrist to control the kettlebell’s offset load.
– Start with the kettlebell over the shoulder, arm vertical, and elbow pointing roughly toward the ceiling.
– Set the upper arm about perpendicular to the torso and keep it still throughout the movement.
– Bend only at the elbow to lower the kettlebell toward the side of your head.
– Stop the descent just before the bell would contact your head or upper arm, with the forearm roughly parallel to the torso.
– Extend the elbow until the arm is straight without hyperextending.
– Keep the elbows from flaring excessively as you lower and press.
– Lower and raise the kettlebell under control, avoiding momentum.
Kettlebell Lying Triceps Extension Skull Crusher Beginner Introduction
The kettlebell lying triceps extension (skull crusher) is a strength exercise performed while lying on a bench or the floor, using a kettlebell in one hand. The arm starts roughly above the shoulder, and the movement centers on bending and straightening the elbow so the kettlebell travels in an arc toward the side of the head and back up. Because the upper arm stays nearly still, the back of the upper arm does most of the work, making this a classic isolation move for the triceps with an emphasis on smooth, deliberate elbow motion.
A kettlebell’s uneven weight places extra demand on the wrist and elbow, calling for a steady, aligned grip and controlled pace. Lightly drawing the shoulder blades together and resting the back in a natural curve creates a solid platform, helping the shoulders stay stable instead of taking over. The motion typically stays within a comfortable path that challenges the triceps while keeping the kettlebell a safe distance from the head.
