Cobra Pose step by step: lift the chest with your back muscles, spare the lumbar spine and use the hands-off test. With Sphinx preparation and mistake fixes.
How high do you have to go in Cobra for it to "count"? The honest answer: not high at all. Cobra (Bhujangasana, "snake") is a backbend from lying on your stomach in which the hands rest under the shoulders and the chest lifts with bent arms. It's not about how far you push up but with what: the back should lift the chest, not the arms.
That is the most important distinction between a useful Cobra and a squeeze of the lumbar spine. The background: back pain is a real topic in yoga. In the Cochrane review of 21 trials with 2,223 participants, the risk of adverse events, mainly worsening back pain, was higher with yoga than with no exercise (43 per 1,000 versus 9 per 1,000, with low certainty of evidence) [1]. Backbends therefore require care.
How hard is Cobra? Very doable as a starter because you only need a few centimetres. The build-up goes through Sphinx, which teaches you the strength before you go higher.
Lie on your stomach, feet hip-width, tops of the feet on the floor. Press the pubic bone lightly into the floor and lightly engage legs and glutes. The forehead rests on the floor, hands under the shoulders, elbows close to the body.
Prop yourself on the forearms and lift the chest. Elbows under the shoulders, shoulders away from the ears. Hold 5 breaths.
Milestone: you hold Sphinx for 5 breaths without the lower back collapsing and without pulling the shoulders to the ears.
Place the hands under the shoulders, elbows pulled back. Inhale and lift head, chest and upper ribs with the back muscles. The elbows stay bent.
Lift the hands one centimetre off the floor. Does the chest stay up? Then your back is working. If it drops, you are still pushing with the arms. This is the most honest test of Cobra.
Milestone to move on: you hold Cobra for 5 breaths, the hands stay light in the test, the shoulders are away from the ears and the neck is long.
Exhale and let chest and forehead sink back to the floor. One round: 3 to 5 breaths, then two to three repetitions. Afterwards a short counter-pose in Child's Pose.
The trunk is the most frequently injured region in yoga: in 14 years of US emergency department data, 46.6% of yoga injuries involved the trunk, most often as a strain (45.0%) [2]. Better low and clean than high and squeezed.
With spondylolisthesis (vertebral slippage), a disc herniation with radiating pain, acute back pain or pregnancy, clarify Cobra beforehand. With numbness or tingling in legs or hands, stop. In the survey of 1,702 yoga practitioners, those who practised only by self-study without instruction had a higher risk of adverse effects [3]. A supervised class helps a lot. This guide explains and motivates; it does not replace supervised training.
Draw the palms invisibly back toward your feet, as if pulling the mat toward you. This activates the muscles between the shoulder blades and opens the chest without pushing with the arms. Combined with the hands-off test you have the most important Cobra check in one minute.
As high as your back carries the chest without the arms pushing. For many that is only 10 to 20 centimetres. The pubic bone stays on the floor. Higher is not a better Cobra, but often a squeeze of the lumbar spine.
In Cobra the arms stay bent, legs and pelvis lie on the floor, and the back muscles lift the chest. In Upward-Facing Dog the arms are straight and pelvis and thighs hover. It demands more strength and wrist load.
Not when done low and with an active back. It becomes problematic when you push up with the arms and hang into the lumbar spine. Yoga was associated with more adverse events than doing nothing for back pain in the Cochrane review [1], so build up carefully.
Two to three repetitions of 3 to 5 breaths each, three to four times a week, is a good start. Pain in the lower back is a stop signal. Do Child's Pose afterwards as a counterbalance.
Only as long as the neck stays long. The gaze goes to the floor or slightly forward, the back of the head follows the extension of the spine. If you throw the head back, you compress the neck vertebrae and take mobility away from the chest. If the neck pinches, keep the gaze down.
