How to Do Kettlebell Lying Triceps Extension Skull Crusher
- 1Setup
Lie supine on a bench or the floor, holding a single kettlebell with both hands, gripping the horn with your palms facing each other. Position the kettlebell directly above your chest with your arms fully extended.
- 2Setup
Ensure your elbows are slightly bent to avoid locking out, and your shoulders are pressed firmly into the bench or floor. Keep your feet flat on the floor for stability.
- 3
Inhale as you slowly bend your elbows, lowering the kettlebell in an arc towards your forehead or slightly behind your head. Keep your upper arms stationary and tucked close to your body.
- 4
Continue lowering until your forearms are parallel to the floor or you feel a deep stretch in your triceps. Avoid letting your elbows flare out.
- 5
Exhale as you powerfully extend your elbows, contracting your triceps to push the kettlebell back to the starting position above your chest. Focus on a controlled movement without momentum.
Tips
- Maintain a stable upper arm position throughout the movement; only your forearms should move to isolate the triceps effectively.
- Control the descent of the kettlebell to maximize time under tension and prevent injury, especially to the elbows.
- Slightly tuck your chin towards your chest to keep your neck in a neutral position and prevent strain during the exercise.
- Use a lighter kettlebell initially to master the form before increasing the weight, prioritizing triceps engagement over heavy lifting.
Common Mistakes
- ×Allowing your elbows to flare out reduces triceps activation and puts undue stress on the shoulder joint; keep your elbows tucked in and pointing forward throughout the movement.
- ×Using momentum to swing the kettlebell up rather than triceps strength compromises muscle engagement; use a controlled, deliberate motion focused on muscle contraction.
- ×Lowering the kettlebell too far past your head can strain the shoulder joint; stop when your forearms are parallel to the floor or you feel a good stretch in your triceps.
