Instructions

  1. 1Secure your legs at the end of the decline bench and slowly lay down on the bench.
  2. 2Using a close grip (a grip that is slightly less than shoulder width), lift the EZ bar from the rack and hold it straight over you with your arms locked and elbows in. The arms should be perpendicular to the floor. This will be your starting position. Tip: In order to protect your rotator cuff, it is best if you have a spotter help you lift the barbell off the rack.
  3. 3As you breathe in and you keep the upper arms stationary, bring the bar down slowly by moving your forearms in a semicircular motion towards you until you feel the bar slightly touch your forehead. Breathe in as you perform this portion of the movement.
  4. 4Lift the bar back to the starting position by contracting the triceps and exhaling.
  5. 5Repeat until the recommended amount of repetitions is performed.

About Decline Skull Crusher

The decline skull crusher changes the classic EZ-bar angle to a decline position, increasing tension on the long head of the triceps, often less worked in standard pressing movements. Lying head-down, you lower the bar toward the forehead before extending the arms, an advanced exercise that requires solid technical mastery and ideally a spotter to unrack the bar.
