HOW: Get set-up sitting upright with a surface next to you to support your elbow and forearm. If not, it is ok you can follow the video example. With your elbow fully extended, position your hand with your palm facing down unsupported at the edge of the surface. While maintaining your forearm and elbow position, use a dumbbell or your other hand to apply an external resistance and perform concentric and eccentric wrist extension. See the video for other tips and instructions.
FEEL: You should feel the muscles on top of your forearm working as well as other muscles in your forearm and hand to help with gripping the dumbbell if you’re using one. You may feel tension on the outside of your elbow as well.
COMPENSATION: Perform slowly, do not lose elbow position, do not lift your arm off the surface.
