Introduction
Bhujangasana appears in almost every yoga class. It’s part of the Sun Salutation sequence, it features in beginner programs, it’s recommended for back health, and it’s one of the first poses most people learn.
It’s also one of the poses most people do wrong — and do wrong consistently, for years, without realizing it.
The common version looks like this: the person lies face down, places their hands near the shoulders, and pushes their arms straight up, lifting the chest aggressively. The back arches, the shoulders hunch toward the ears, the lower back compresses, and the actual muscles of the back do almost nothing because the arms did all the work.
That’s not Bhujangasana. That’s something else dressed in Bhujangasana’s clothes.
Bhujanga means serpent or cobra. The pose mimics the raised hood of a cobra — a gradual, muscular lift from the ground, not a push.
How to Do Bhujangasana
Lie face down with legs extended, tops of the feet on the floor. Place the hands under the shoulders, fingers spread, elbows close to the ribs.
Here’s the instruction most classes skip: before moving, engage the back muscles. Draw the shoulder blades toward each other and slightly down. Feel the muscles along the spine begin to activate.
Now inhale and let the back muscles lift the chest. The arms assist — they don’t lead. In a well-practiced Low Cobra, the elbows remain bent and the lift comes predominantly from the spinal extensors. The hands are on the floor but barely bearing weight.
How high you go depends on your back’s capacity, not your arm strength. Some people lift 4 inches; some lift 12 inches. The right height is where the lower back feels lengthened and extended, not compressed and crunched.
If you go into a higher version, the arms straighten more — but even then, the back muscles should be doing the primary work. Shoulders stay down and back, away from the ears.
Hold for 15 to 30 seconds. Exhale and lower slowly, with control.
Benefits of Bhujangasana
Spinal extensor strengthening. The erector spinae and multifidus muscles — the muscles running alongside the spine — are the primary workers in a properly executed Bhujangasana. These muscles are crucial for posture and lower back health. Most office workers have weak spinal extensors from sitting in flexion all day. Cobra, done correctly, directly addresses this weakness.
Chest and anterior shoulder opening. As the chest lifts, the pectoral muscles and front of the shoulder stretch. This counteracts the internal shoulder rotation that develops from keyboard use, driving, and phone habits.
Hip flexor stretch. The prone backbend position lengthens the iliopsoas and rectus femoris, which shorten with prolonged sitting.
Lower back rehabilitation. For certain types of disc issues — specifically, anterior disc bulges that cause pain with forward bending — spinal extension exercises like Cobra are specifically prescribed in physiotherapy. The loading pattern of prone extension creates a posterior movement of disc material, which can reduce nerve pressure. This is specific to certain disc presentations; consult a physiotherapist before using Cobra therapeutically.
Abdominal stretch. With the chest lifted, the rectus abdominis (and deeper abdominal muscles) stretch. This is a direct counter to the compression these muscles experience during forward bends and sitting.
Tips for Better Practice
- Try Low Cobra first. Lie face down, put your hands lightly on the floor, and lift the chest using only the back muscles, with the hands barely pressing. Go only as high as the back muscles can take you without the arms kicking in. This is the real pose. Practice this for weeks before adding arm involvement.
- Keep the elbows close to the ribs. Elbows splaying outward is a sign the arms are doing too much and the back isn’t working.
- Soften the glutes. Many people clench the glutes in Cobra, which actually restricts lumbar extension. Lightly engaged or completely relaxed glutes allow the pose to work more freely.
- Don’t crunch the neck. The head should follow the natural arc of the spine — a gentle lifting of the gaze, not a sharp backward crank of the neck.
- Press the pubic bone gently into the floor. This creates a counter-resistance that protects the lower back and deepens the abdominal stretch.
Why Learn with a Yoga Teacher or Instructor
The difference between a back-muscles-led Cobra and an arms-led push is very hard to feel from the inside when you’ve only ever done the arm-led version. A teacher can place a hand on the mid-back and ask you to lift into it, which gives immediate tactile feedback about what the back muscles actually feel like when they’re working.
Teachers also catch the shoulders creeping toward the ears — an extremely common compensation that loads the trapezius and neck rather than opening the chest — and the lower back compression that comes from going higher than the back muscles can actually support.
Getting this pose right early saves years of doing it in a way that doesn’t build what it’s meant to build.
Cautions and Contraindications
- Herniated lumbar disc (posterior herniation): Spinal extension can increase posterior disc pressure. Get clearance from a physiotherapist. For anterior disc bulges, extension may actually help — but this needs individual assessment.
- Carpal tunnel syndrome or wrist injuries: Practice on fists, or place the forearms on the floor (Sphinx Pose variation) to reduce wrist load.
- Pregnancy: Do not lie prone after the first trimester.
- Recent abdominal surgery: The prone position and the abdominal stretch are contraindicated until surgically cleared.
- Severe spondylolisthesis: Lumbar extension is contraindicated without specific guidance from a spine specialist.
Conclusion
Bhujangasana is a pose that rewards technical attention. Done casually, it’s a mild back stretch. Done correctly — with the back muscles leading, the arms assisting, the chest opening rather than the lower back compressing — it’s one of the more therapeutic postures in yoga for modern bodies.
The version worth practicing is the one most people haven’t tried yet. Low Cobra. Back muscles doing the work. Hands barely on the floor.
Start there. Everything else follows.
