Muscles involved: The extensor muscle corresponding to the finger being flexed
The Finger by Finger Flexion, as the name reveals, is done one finger at a time. Simply hold on to each finger individually with the opposite hand and produce a deep but gentle flexion. The wrist must remain flexed at approximately 90°.
During the exercise, flex the wrist slightly with each pull of the finger in order to put even greater emphasis on the tension. Of course, as in all other stretching exercises, the movement here should also be slow and controlled.
