A solid workout routine for stronger and more mobile shoulders is essential for athletes. Luckily, fitness coach Jeff Cavaliere shared his perfect shoulder workout. Cavaliere, a former New York Mets physical therapist, now shares fitness advice on his popular ATHLEAN-X YouTube channel. Properly training the intricate shoulder joint, with its 3-dimensional structure and multiple muscle heads, is crucial for balanced development and injury prevention. Cavaliere’s workout targets all parts of the shoulder girdle through stretches and exercises for a well-rounded and proportionate result.
