You know what happens when a practitioner takes a big step forward with her right foot?
In the old days, I’d assume she was preparing for Warrior I (Virabhadrasana I), Revolved Triangle (Parivrtta Trikonasana) or some other standing posture. So, I’d hang back and wait for the pose to develop.
But since I started studying and collaborating with movement specialists from the Gray Institute, I’ve learned that the key to developing and enhancing Yoga practices, to preventing injuries, and to helping rehab aches and pains is bringing awareness to how eeach aspects of the practitioner’s body flows from one movement to the next.
I have been amazed to observe that in every movement, no matter how gross or how subtle, there’s a vinyasa within the vinyasa (a sequence within the sequence) that unfolds moment to moment.
Most often when a practitioner steps forward, three subtle but incredibly significant things happen:
- First, the outer border of her heel hits the mat and the force of that impact (the ground reaction force) everts her heel (her calcaneous pronates), tipping it sideways towards the big toe side of her foot.
- At the same time, rotational movement (abduction) is created where the calcaneus and the bone sitting on top of it, the talus, meet (this juncture is called the subtalar joint).
- Meanwhile, just above the talus, gravity and the practitioner’s mass and momentum bring her two lower leg bones (the tibia and the fibula) forward, creating ankle dorsiflexion (a bending that brings the toes and top of the foot closer to the ankle joint).
At first glance, these responses may not seem significant. I didn’t pay close attention to them for years.
“So the heel strikes the mat. It creates subtalar eversion, subtalar abduction and ankle dorsiflexion. Big whoop.”
Except that each of those movements was just given “for free.” An instructor didn’t cue them nor did our fellow practitioner have to “think” to make them happen. The dorsiflexion, eversion and abduction were all gifts, complements of gravity working with the practitioner’s mass and momentum against the resistance that the ground provided. To anyone interested in deepening her practice, preventing injuries, or rehabbing aches and pains that is actually a very big whoop.
Watch what the body does with those gifts: Continue reading
