How to rehab your latissimus dorsi muscle | The MSK Physio
The latissimus dorsi, or lats are an enormous muscle with attachments at the front of the upper arm bone (humerus), from just below your shoulder blades at the spine (thoracic level 7) all the way down to the bottom of your lower back and pelvic bone. Along that journey it also has connections with ribs 9-12 (Drake et al., 2009). We know that if a muscle connects to a region it can create movement at that region.
Of interest in this video is the action it performs on the arm. This is internal rotation, extension and adduction! We know that from specific EMG studies this recruits the most fibres of the lats (Park & Yoo, 2013; Rota et al., 2013; Smith et al., 2004). Importantly, a pulling from overhead component must be included in the form of a seated lat pull-down or a chin up, to achieve maximum muscle fibre recruitment!
