Show Notes
The muscles responsible for extending the shoulder, hip, elbow, and knee are the latissimus dorsi, gluteus maximus, triceps, and quadriceps, along with several assisting muscles in each movement. This “NASM CPT Podcast” episode answers the popular question, "Which muscles extend your shoulder, hip, elbows, and knees?"
Host Rick Richey breaks down the primary and secondary muscles involved in these extensions, explains their functions during movement, and clarifies the anatomical meaning of extension and the planes of motion where these joint actions occur. Listeners will learn to distinguish which muscles play a main role and which assist during shoulder and hip extension as well as the more straightforward actions in the elbow and knee. The distinctions between major and minor contributors, such as the teres major alongside the latissimus dorsi for the shoulder or the hamstrings assisting the gluteus maximus at the hip, are clearly described.
By the end of this episode, NASM students, trainers, and anyone seeking functional anatomy clarity will be able to confidently identify and articulate which muscles extend the body's major joints and how they work together during exercise.
