Can forcing a muscle stretch hurt you

Once the muscle spindle acclimates to the milder stretch, activate the quadriceps to straighten the knees and deepen the pose. Engaging the quadriceps inhibits the reflex contraction of the hamstrings caused by the muscle spindle.

It may seem counterintuitive, but we can actually deepen a stretch by first backing off on the stretch.

As with the hamstrings, you can dissolve the reflex contraction of the erector spinae by slightly relaxing the stretch. This decreases the firing of the muscle spindle stretch receptors.

Do this for the erector spinae by lifting the back slightly from the hips. Hold this milder stretch for a few breaths.

Once the muscle spindle of the erector spinae acclimates to the milder stretch, contract the psoas and rectus abdominis to flex the hips and torso and deepen your pose. Engaging the psoas inhibits the reflex contraction of the erector spinae.

Yoga Practice Tips:

You can use this technique to deepen any posture that stretches your muscles. It is an excellent technique if you are new to yoga or teaching practitioners who are new to yoga. It also works well if you have not stretched in a while.

In summary, work with the muscle spindle as follows:

1) Back off approximately 20% from a full stretch. Make sure you feel a mild stretch so that some of the muscle spindles are still firing.

2) Hold the milder stretch for 3 to 4 breaths to acclimate the muscle spindle and reassure it that you are stretching safely.

3) Then, with control, carefully go deeper into the pose by engaging the opposing muscle group.

If you are new to integrating anatomy into your practice, remember that it is not necessary to memorize this technique on your first pass. Begin by enjoying the beautiful images of the body in yoga. This alone will awaken your brain’s awareness of the anatomy during your practice. Return at a later date for a closer look and then gently go through the motions illustrated above as you do this pose. Then leave it. Your unconscious mind will create new circuitry while you rest. Enjoy the process and when you return to the mat, you will be surprised at how easily you access this technique.
