Loads the elbow. Use a load you can control and skip it if it causes pain.

How to do it

  1. Adjust the seat to the appropriate height and make your weight selection. Place your upper arms against the pads and grasp the handles. This will be your starting position.
  2. Perform the movement by extending the elbow, pulling your lower arm away from your upper arm.
  3. Pause at the completion of the movement, and then slowly return the weight to the starting position.
  4. Avoid returning the weight all the way to the stops until the set is complete to keep tension on the muscles being worked.
