Decline skull crushers place you on a slight decline angle, which increases the stretch on the long head of your triceps compared to flat skull crushers. The decline also allows the bar to travel further behind your head, creating greater range of motion and tension at the stretched position.
When to use it
Use for long head emphasis with increased stretch.
Who it's for

Set the bench to a slight decline (15-30 degrees) and secure your feet. Lower the bar toward your forehead or behind your head while keeping your upper arms stationary. The decline makes controlling the weight more challenging, so start lighter than flat skull crushers.

Moving upper arms for optimal results.
During any pressing movement like the Decline Skull Crusher, this mistake reduces how effectively your Triceps (long head) can produce force. Focus on the muscle you're trying to work — if you can't feel your Triceps (long head) driving the movement, something is off.
Using too much weight.
