In The Key Muscles of Yoga, I point out that athletes experience improved performance and fewer injuries when they have a fundamental knowledge of their anatomy and biomechanics. For this reason, I recommend that you add The Daily Bandha to your favorites and return every day or so to review one or two of the concepts presented here. This will allow you to integrate these tools into your yoga practice. After just a few sessions, you’ll begin to apply the techniques unconsciously, improving your poses and aiding to prevent injuries.
In our last post, we discussed the concepts of joint congruency and joint reaction forces as related to yoga. These are among the most important principles to understand for both practitioners and teachers, because many poses can take the articulations to the limits of their range of motion. Take a moment to review this post and look at the new video which shows these concepts in action in Padmasana (Lotus Pose).
Now, on to releasing the internal rotators of the hip . . .
The main muscles that internally rotate the femur at the hip are the tensor fascia lata (TFL) and gluteus medius. The gluteus minimus contributes to this action when the hip is flexed. Conversely, when the internal rotators are tight, they can limit external rotation of the joint, a key component in poses like Lotus. Practicing this asana without releasing the TFL and gluteus medius can lead to excessive joint reaction forces in the knee. This is because the rotational component of the pose is directed into the knee. The key is to use the hip (which is a ball and socket joint) to do the rotation, while protecting the knee by maintaining it as a hinge.

Tensor fascia lata and gluteus medius stretching. |
To release the TFL and gluteus medius, I use a technique called the “cradle stretch.” In it we lift the lower leg, as shown here. This action externally rotates the hip. Do not allow the knee to sag forward away from the body—this is important. Cradle it in the crook of the elbow so that the knee is maintained as a hinge. Place the outer edge of the foot into the crook of the other elbow and engage the peroneus longus and brevis muscles at the outside of the lower leg to evert the foot. Extending the toes also helps. This aids to maintain the congruency of the knee joint and helps to protect it from injury.
