In this blog post we examine the rectus femoris muscle and its relation to yoga poses, beginning with an overview of the muscle and how it stretches. Figure 2: The rectus femoris contracting to flex the hip and extend the knee in Supta padangustasana. Stretching the rectus femoris is best accomplished in poses that combine hip extension and knee flexion. Feel free to browse through The Key Muscles of Yoga and Key Poses of Yoga by clicking here.The Yoga Mat Companion Series gives you step-by-step anatomic sequencing for all of the major asanas, with a variety preparatory poses as well. Always, in your particular case, consult your health care provider and obtain full medical clearance before practicing yoga or any other exercise program.

We conclude with some interesting synergy that can occur between the rectus femoris and the gluteus maximus in poses where both the hip and knee are extending, such as Warrior I.

It runs from the anterior inferior iliac spine to the quadriceps tendon, which attaches to the patella or knee cap.
It also acts as a synergist of hip flexion and has increased activity with abduction and external rotation of the hip joint. Poses like Virasana (with the hips flexing) are good for stretching the other heads of the quadriceps, however, a reclining variation is necessary to lengthen the rectus femoris.
The gluteus maximus is a hip extensor and, thus, an antagonist of the rectus femoris for this action. Stay tuned for our next post when I'll present another subject on combining science and yoga. If the foot is fixed on the mat, contracting the gluteus maximus tilts the pelvis as shown (closed chain action).
We’re also pleased to announce that all of our books are now available in digital format for Kindle and other devices. Practicing under the direct supervision and guidance of a qualified instructor may reduce the risk of injuries. The rectus femoris thus crosses both the hip and the knee, making it a bi-articular muscle.
Tilting the pelvis back and down creates a pull on the rectus femoris, which is transmitted to the knee joint, leading to more efficient knee extension.

As a teacher i wish to share your knowledge of anatomy with my student i have your books and these posts remind me i need to re read them. Note that the other three heads of the quadriceps muscle only cross the knee joint and are mono-articular (figure 1). Practicing under the direct supervision and guidance of a qualified instructor, in addition to the direction of your health care provider, can also help determine what poses are suitable for your particular case.

I find the diagrams, anatomy and explanations all combine to help me visualise, understand and enjoy my yoga. Then the hip extension also puts the rectus femoris under further tension, which augments the knee extension.
