With your hand open, palm up and the thumb pointed as if you are hitch hiking you can see and palpitate, the flexor digitorum profundis on the inside of the upper half of your forearm. The muscle originates from the anterior and medial elbow (ulna), then goes about half way down the forearm. The muscles long tendons extend through the carpal tunnel at the wrist and attach to each finger. The flexor digitorum profundis flexes the joints of the index, middle, ring and little fingers. Since all four tendons come together at or below the wrist a contraction of the muscle produces a mass action, whereby it allows for a powerful grip. To effectively train this muscle the Pendulum Power Grip Pro is the perfect tool to Get Strong.
