How to do the decline skull crusher

Last Updated onFebruary 27, 2021

The decline skull crusher is a tricep extension variation which works all three heads of the tricep. It’s very effective for packing on lots of size and gaining strength which is why it’s one of the best tricep exercises overall. Now, anyone can perform this exercise as long as the elbows are properly warmed up, and this is important to keep the stress of the elbows and on the triceps.

If you’re looking for a simple movement to incorporate into your tricep routine then the decline skull crusher should be a staple exercise.

Using a decline bench allows more tension during the exercise and that’s why it’s so effective for making gains!

Exercise Instructions

Lie on a decline bench while holding a barbell straight up in the air directly above chin level. Use a pronated shoulder-width grip.
Keep your elbows tucked in while keeping your upper arms still, then slowly lower the barbell to your forehead while exhaling.
Now, use your triceps to power the weight back up until your arms are almost straight but don’t lock out your elbows at the top. Inhale during this portion of the exercise.
Repeat for the desired number of reps.

Warm up thoroughly to protect the elbows and feel the contractions in the triceps.
