Dumbbell Skull Crusher

How to do it

1. 1

   Lie on your back with knees bent and hold the dumbbells above your shoulders with palms facing each other. Breathe in and settle into the starting position.

2. 2

   Breathe out as you bend your elbows, roll the dumbbells beside your head, then extend and press them back above you.

3. 3

   Breathe in as you reverse the small rolling path until the dumbbells return beside your head.

4. 4

   Breathe out as you steady the weight and prepare for the next controlled rep.

Where you should feel it: The backs of your arms.
