In this “NASM-CPT Podcast,” host Rick Richey takes listeners on an engaging, in-depth exploration of the quads—the powerful muscles of the front thigh affectionately known as "thunder thighs" and “Quadzilla." Rick dives into the fascinating anatomy and function of the quadriceps muscle group, breaking down its four key components: the vastus lateralis, vastus intermedius, vastus medialis (including the notable vastus medialis obliquus or "VMO"), and rectus femoris. Listeners will learn the meaning behind the "quad" name, discover the origins and attachment sites of each muscle, and understand why these muscles are considered a group yet remain distinct in structure and function. Rick masterfully explains joint actions such as knee extension and hip flexion, the unique role of the rectus femoris as a two-joint muscle, and how the design of the quadriceps provides mechanical advantages for movement. Practical guidance also awaits, including tips on properly stretching the quads and understanding how and why certain stretches target different parts of the muscle group. Dr. Richey shares relatable analogies, memorable mnemonics, and everyday fitness advice, making complex biomechanics easy to understand and apply.
