Let the Lumbar Curve Be
By Paul Grilley
Some yoga instructors insist that students avoid curvature of the spine by insisting on tucking the pelvis. But any healthy movement can be overdone. Rather than insist on always having the pelvis tucked encourage your students to utilize the full range of pelvic motion in their practice.
Bad News Ballet?
The idea that a “tucked pelvis” is good for you comes from ballet. Ballerinas are taught to tuck their pelvis so they can spin on a straight axis. It is difficult to spin multiple times if the pelvis is not tucked. Ballerinas are also taught to tuck their pelvis so they can maximize the height and appearance of leg extensions. Many yoga instructors are former dancers and it is habitual for them to remind students to tuck their pelvis.
If ballet is bad for you, why imitate it?
Well, number one: ballet is not bad for you. Much of ballet training is about balance, stretching, and learning to isolate movements. This is good for you. Number two: tucking the pelvis is a natural movement you should learn how to do. It only becomes destructive if you remain stuck in that position.
Is an arched pelvis better than a tucked pelvis?
The last two covers of Yoga Journal magazine feature photos of young women in deep backbends. This is the opposite movement to a tucked pelvis. The poses look beautiful and one can’t help but admire the ease and range of motion of the models. But I doubt if anyone would think it healthy for someone to habitually hold their spine in this deep bend. If anyone attempted to do so, the discs in their back would degenerate painfully.
Then is a neutral position best?
Constantly arching the spine is unhealthy. Constantly tucking the spine is unhealthy. So should we live our lives in a timid neutrality of spine position, neither tucking nor tilting the pelvis? The answer is an emphatic “No!” The neutral spine position is how office workers live their lives, and statistics show that 80 percent of them will suffer serious back problems.
Inhale and exhale, tuck and arch, life is about movement.
To have a healthy spine, we must systematically move it through its full range of motion. This means sometimes we tuck the pelvis to flatten the spine, sometimes we tilt the pelvis to arch the spine, and sometimes we keep the spine neutral. This is the Taoist view of life, a constant alternation from one opposite to another. The contraction and expansion of the heart are opposites, but by alternating they are the Tao of circulation. The expansion and contraction of the lungs are opposites, but by alternating they are the Tao of breathing. Tucking and tilting the pelvis have opposite effects on the curve of the spine, but by alternating they are the Tao of posture.
Tuck it and arch it.
When practicing backbends such as the Cobra, don’t try to tuck the pelvis but let the spine arch. When practicing forward bends such as Paschimottanasana, don’t try to tilt the pelvis but let the spine round. These are normal movements for the lumbar spine, and to fight against them is to nullify the effects of the poses. Of course, overstretching an already injured spine could make it worse. But sooner or later, the goal of all physical rehabilitation is to regain the natural range of motion. Yoga practice helps us retain our full range of motion so we can easily alternate from a tucked pelvis with a straight spine to a tilted pelvis with an arched spine. Both these movements are necessary to maintain healthy posture.
