We cover the lat and posterior RC in detail in the advanced course. I agree it adds huge value, especially in the throwing athlete. We also cover the flexor mass in the forearm in more detail in the advanced course with specifics to median, ulnar, and musculocutaneous nerve distributions, entrapment, and emergent points. In the forearm you can follow extremity needling guidelines and focus on symptomatic points. I would take general care around the major nerve branches, brachial artery, and visible veins but nothing necessarily dangerous.
