SINGLE-ARM DB SKULLCRUSHER

Exercise Instructions:

  1. Lie on a flat bench with a dumbbell in one hand.
  2. Extend your weighted arm up above your chest and rotate the dumbbell into a neutral-grip.
  3. This is not the start position. There isn’t much tension on the triceps in this position because the chest and shoulders are acting as our supporting muscles. Keeping your arm straight, extend back until the dumbbell is above eye level, instead of chest level. Now we have tension in our triceps, this is where we start each rep.
  4. Bend at the elbow to lower the weight down behind your forehead, then power the dumbbell back to the start point by driving it through your triceps.

Muscles Worked:

Triceps.
