1. Begin by lying on your back on a bench with an EZ bar straight overhead so that your arms are facing up towards the ceiling.
  2. From here, bend at your elbows to initiate the skullcrusher movement and from there allow the bar to carefully rock back behind your head adding extra strain onto the triceps.
  3. Return back to the skullcrusher position and then back to the starting position with your arms straight overhead.
