HOW: Anchor a band underneath your foot while seated. Lean over and place your forearm on top of your knee with your palm facing down and pointing to your other knee. Grab the anchored band and while keeping your forearm stabilized on your thigh, move your wrist up and down. If you need more resistance, shorten the length of the band between your foot and hand.
FEEL: You should feel the muscles in your forearm working.
COMPENSATION: Don’t move your arm or shoulder while extending your wrist. Keep the arm stabilized on your thigh.
