Surya Namaskar, or Sun Salutation, is a foundational practice in yoga that involves a rhythmic sequence of twelve linked physical postures, or asanas. This dynamic series is performed in a fluid, continuous motion, often synchronized with the breath. While many people seek its holistic benefits, a frequent question concerns its effectiveness as physical exercise: how many calories does a Sun Salutation session burn? The answer is not a single fixed number, as the energy expenditure depends entirely on how the sequence is performed, but scientific estimates provide a helpful range.
The Estimated Calorie Burn Rate
The calorie expenditure during a Surya Namaskar session is measured using the Metabolic Equivalent of Task (MET) system, which provides a standard measure of energy cost. A general, moderate-paced practice of Sun Salutation yoga is often assigned a MET value of approximately 3.3. This value represents the energy expended relative to sitting quietly, meaning the practice burns 3.3 times the calories consumed at rest.
Using this general MET value, a person weighing about 150 pounds (or 68 kilograms) performing the sequence for 30 minutes would burn roughly 112 to 115 calories. However, many practitioners perform the sequence at a much faster, more vigorous pace, which dramatically increases the caloric output. Studies comparing different speeds show that a slow, meditative pace might burn around 3.30 kilocalories per minute, while a fast, athletic pace can increase that to over 5.4 kilocalories per minute.
For a more intense practice, some estimates suggest that one round of the Sun Salutation sequence can burn nearly 14 calories for an average-weighing individual. If a person completes 12 rounds in a 10-minute period at a vigorous pace, they could burn well over 100 calories in that short time frame. A sustained, intense 30-minute session of fast-paced Surya Namaskar has been estimated to burn as much as 300 to over 400 calories, placing it in the category of a challenging cardiovascular workout.
Variables That Change Energy Expenditure
The wide range of calorie burn estimates highlights that the intensity of the practice is not standardized and depends on several individual and technical factors. Body weight is a primary factor because the calculation for energy expenditure is directly proportional to mass. Simply put, heavier individuals require more energy to move their body through the series of poses, resulting in a higher total calorie burn for the same duration and intensity.
The speed or pace of the transitions between the twelve poses is perhaps the greatest determinant of caloric output. A slower, more deliberate rhythm maintains a lower heart rate, making the exercise more meditative and less demanding on the cardiovascular system. Conversely, moving quickly and fluidly through the sequence elevates the heart rate, increasing oxygen consumption and pushing the practice toward an aerobic workout level.
The technique and depth of the poses also play a significant role in energy expenditure. Holding poses like Plank or Chaturanga Dandasana (low plank) with proper form requires substantial static and dynamic muscle engagement. Deeper lunges and more active muscle stretching demand greater effort, activating more muscle fibers and increasing the overall energy required. The total duration of the practice is also a direct multiplier, resulting in greater total caloric expenditure.
Comparison to Common Exercises
To put the energy cost of Surya Namaskar into perspective, its calorie-burning potential can be compared to other familiar activities. A moderate-intensity Sun Salutation practice, falling around the 3.3 MET level, is comparable to the energy cost of walking at a brisk pace. This pace provides a solid baseline for cardiovascular health and general fitness maintenance.
However, when performed with vigor and speed, the calorie burn rate of Surya Namaskar begins to approach that of more demanding exercises. An intense 30-minute session can match the caloric output of running at a speed of 7.5 miles per hour or cycling at a high intensity. Studies have shown that 30 minutes of very fast-paced Sun Salutations can burn roughly the same number of calories as running at a high speed. This intense output is significantly higher than the burn from light activities like weight training or standard Hatha yoga, which often have lower MET values.
