Description

Let’s get your week kicked off just right with a deep dive into Greek alphabet.


On this episode of the “NASM-CPT Podcast,” host, and NASM Master Instructor, Rick Richey, explores the large, triangular shoulder muscle, named because its shape resembles the Greek letter, Delta.


Dr. Richey discusses the three distinct heads of the muscle (anterior, lateral, and posterior), as well as the actions of the deltoids with specific examples to help expand your personal training, and anatomy, expertise.
