Comments and tips

  • Keeping your elbows in will prevent the involvement of your pectorals and anterior deltoids and keep the emphasis on your triceps brachii.
  • Ensure that the cable is taut throughout the repetition.
  • Use a wavy bar if the straight bar is hard on your wrists.
  • Avoid going heavy with this exercise if it hurts your elbows.
