Latissimus Dorsi Stretch

Latissimus Dorsi

The Latissimus Dorsi muscle is the main extensor muscle of the arm. It is heavily involved in exercises such as swimming freestyle (front crawl) and performing chin-ups. It is also referred to sometimes as the ‘hand-cuff’ muscle as this is the main action that the muscle performs in bringing the arms and hands behind the back.

Latissimus Dorsi StretchOption 2 ~ Using a pole or anchor in front of you, position your body in a walking stance (one foot forward, the other behind), with opposite hand to the forward foot, grasp the anchor, bend forward at the waist and flex the spine into a curved position. Now, twist or rotate your torso to look underneath that arm that you have locked upon the anchor and lean your body weight towards your back foot. If you would like to increase the intensity of the stretch, just lean further rearward and twist further under the arm.
