Step by step

  1. Set a cable pulley in a low position and attach a handle.
  2. Select a light load with a pin.
  3. Reach down and grab the handle with one hand.
  4. Turn your body away from the cable machine and extend your arm toward the ceiling.
  5. Place your opposite hand on your elbow for support, retract your shoulder blades, and engage your abs.
  6. Take a breath and slowly bend your elbow until you feel a stretch in your tricep.
  7. Flex your tricep to extend your arm and exhale near the top.
  8. Once finished training one tricep, grab the handle with your opposite hand and do the same number of reps.
