Surya Namaskar, commonly called Sun Salutation, is a flowing sequence of yoga postures performed one after another, synchronized with your breathing. A single round typically takes one to two minutes and moves through 12 positions that stretch and strengthen the entire body. It’s one of the most widely practiced routines in modern yoga, used as both a warm-up and a standalone workout.
Where Surya Namaskar Comes From
Despite its deep association with yoga, Surya Namaskar was not originally considered an asana or part of traditional yoga at all. Sun worship has ancient roots across cultures: the Persians honored Mithras, the Greeks had Apollo, the Egyptians worshipped Osiris, and in India’s Vedic period, hymns to Surya (the sun god) appear in the Krishna Yajur Veda, where a chapter of 132 verses called “Surya Namaskar” describes chanting the twelve names of the sun alongside physical salutations.
The physical sequence most people practice today is much newer. It was conceived and popularized in the 1920s by the King of Aundh, Shrimant Balasaheb Pant Pratinidhi, and later refined by influential teachers like Krishnamacharya, who drew on traditional Indian gymnastic exercises called “danda” movements. From there, major yoga schools including the Bihar School of Yoga and the Sivananda Yoga Vedanta center created their own simplified versions, folding the practice into modern yoga as we know it. Surya Namaskar became a blend of two systems: Indian physical culture and yoga.
The 12 Positions in a Standard Round
One complete round moves through these postures, with each transition linked to either an inhale or an exhale:
- Mountain Pose (Tadasana): Standing tall with hands at your chest in prayer position.
- Upward Salute (Urdhva Hastasana): Arms sweep overhead as you gently arch back.
- Standing Forward Bend (Uttanasana): Fold forward from the hips, hands toward the floor.
- Standing Half Forward Bend (Ardha Uttanasana): Lift your chest halfway, lengthening the spine.
- Plank: Step or jump back into a push-up position.
- Four-Limbed Staff Pose (Chaturanga Dandasana): Lower your body close to the ground, elbows tucked.
- Upward-Facing Dog (Urdhva Mukha Svanasana): Press your chest forward and up, opening the front body.
- Downward-Facing Dog (Adho Mukha Svanasana): Lift your hips into an inverted V shape.
- Low Lunge (Anjaneyasana): Step one foot forward between your hands.
- Standing Half Forward Bend: Return to the halfway lift.
- Standing Forward Bend: Fold fully again.
- Upward Salute: Rise to standing with arms overhead, then return hands to prayer.
To complete a full cycle, you repeat the sequence on the opposite side, stepping the other foot forward in the lunge. This means one full cycle is actually two rounds.
Variations Across Yoga Styles
The sequence above is a common Hatha yoga version, but it’s not the only one. In Ashtanga yoga, Sun Salutation A is a streamlined 9-pose sequence, while Sun Salutation B expands to 17 poses by incorporating a chair pose and warrior I. Some lineages begin every class with several rounds of Sun Salutation before moving into other postures. The core principle stays the same across all versions: link breath to movement in a continuous flow.
Calories Burned and Cardiovascular Intensity
Surya Namaskar is more physically demanding than it looks. Research published in the Journal of Bodywork and Movement Therapies measured participants reaching 80% of their maximum heart rate by the second round, climbing to 90% by the fourth. That intensity is enough to produce a genuine cardiorespiratory training effect, comparable to moderate-to-vigorous aerobic exercise.
A 30-minute session burns roughly 230 calories for someone weighing 60 kg (about 132 pounds). At a faster pace, a 70 kg person can burn between 230 and 330 calories in the same time frame. For a shorter session, 12 rounds at a moderate pace burns approximately 50 to 100 calories depending on your body size and speed. That makes it a viable option for weight management, especially for people who prefer bodyweight exercise over running or cycling.
Flexibility and Strength Gains
The repetitive cycle of stretching and strengthening in each round has measurable effects on flexibility. A study of 100 school-aged children found significant improvements in trunk flexibility after practicing Surya Namaskar, with spinal mobility scores increasing from an average of 5.37 cm to 6.17 cm on a standard flexibility test. Another study on 50 female participants performing just 10 slow rounds with 10-second holds showed immediate improvements in hip and trunk flexibility.
These results hold across age groups and fitness levels. Research on college-aged men found notable improvements in both flexibility and abdominal strength with regular practice. The mechanism is straightforward: each round takes your spine through its full range of motion (forward folds, backbends, and neutral positions), while also loading the shoulders, core, and legs through weight-bearing positions like plank and low push-up.
Effects on Breathing and Lung Capacity
Because every movement is paired with an inhale or exhale, Surya Namaskar essentially functions as a breathing exercise embedded in a physical workout. A study on medical students found that regular practice significantly increased vital capacity (the maximum amount of air the lungs can move), tidal volume (the air exchanged in normal breathing), and expiratory reserve volume. The researchers attributed this to mild widening of the airways and improved communication between the lungs and the brain’s breathing centers. Over time, the stretch receptors in lung tissue become better calibrated, leading to more efficient oxygen exchange.
Stress and Relaxation Response
The combination of rhythmic movement and controlled breathing activates what’s known as the body’s relaxation response, a well-documented shift away from the fight-or-flight state. Regular yoga practice, including Surya Namaskar, has been shown to reduce cortisol (the body’s primary stress hormone), lower resting heart rate, and improve the nervous system’s ability to regulate itself. Neurophysiologists at Harvard Medical School have confirmed that hatha yoga practices trigger this relaxation response.
There’s also an interesting training effect at work. The physical challenge of the practice acts as a controlled stressor, and the body adapts by building greater reserves for handling stress in general. This process, sometimes called supercompensation, means you become more resilient to everyday stressors because your body has practiced recovering from a demanding physical stimulus.
Who Should Be Cautious
Surya Namaskar involves deep forward folds, backbends, and weight-bearing on the wrists, which means certain conditions call for modifications or avoidance. The backbending positions can aggravate hernias and should be skipped during pregnancy. The forward folds put strain on the lower back and are risky for people with disc problems, spondylitis, or sciatica. The plank and low push-up positions load the wrists heavily, making them problematic if you have carpal tunnel syndrome or a wrist injury.
If you have high blood pressure, heart problems, or arthritis, a gentler approach or a modified sequence is a better starting point. For most healthy people, the main risk is simply doing too much too soon. Starting with 2 to 4 slow rounds and building gradually gives your joints and muscles time to adapt.
How to Start Practicing
Traditionally, Surya Namaskar is performed at sunrise, facing east, which ties back to its origins as a salutation to the sun. Practically, morning practice has the advantage of warming up a stiff body and setting a physical baseline for the day. But the sequence works at any time on an empty or light stomach.
Beginners often start with 2 to 4 rounds, focusing on learning the transitions and matching breath to movement. A common progression is to add one or two rounds per week until you can comfortably complete 12 rounds, which takes most people about 15 to 20 minutes at a moderate pace. Slowing down and holding each posture for a few breaths builds strength and flexibility faster than rushing through the sequence. Picking up the pace, on the other hand, shifts the emphasis toward cardiovascular conditioning. Most experienced practitioners mix both approaches depending on what their body needs that day.
