HOW: Get set up ideally with your forearm supported on a surface with your hand off the edge. Perform the exercise by bending and flexing just your fingers to make a fist, then extend and straighten your fingers and repeat.
FEEL: This should feel like gentle motion at your fingers and hand, perhaps you may feel a stretch in your wrist and forearm.
COMPENSATION: Try to limit movement to your fingers, not your wrist
