The LATS originate it a fab that runs from the t spine to the scapula, then down to the lower ribs and pelvis. Contralateral training is good at getting a good stretch of the fibers that originate from the t spine. Ipsilateral training gets the fibers that originate from the bottom of the scapula, the iliac crest, and the lower ribs. #lats #backworkout | Judd Lienhard
