Sorry, But Yoga Might Not Count Toward Your Weekly Exercise Goals

Amanda MacMillan

Do you rely on yoga to meet your 150 minutes of moderate physical activity in a week? You might actually be falling short of your goal, suggests a new review of studies on the physical benefits of the popular mind-body practice. That’s because not all forms of yoga are intense enough to count as moderate exercise—although, depending on how you practice, certain styles certainly can be.

It’s estimated that as many as 20.4 million Americans practice yoga. With its increasing popularity, says study author Enette Larson-Meyer, PhD, it’s important for students and health professionals to understand exactly what type—and how intense—of a workout it really provides. Larson-Meyer is an associate professor at the University of Wyoming, and a certified yoga instructor.

Her new research looks at 13 previously published studies on Hatha yoga and several of its variations. Hatha is an umbrella term that describes a practice that integrates physical postures, breathing, and meditative elements; popular Western styles such as Vinyasa, Ashtanga, and Bikram can all be considered branches of Hatha yoga.

The review,

published in the journal Medicine and Science in Sports and Exercise, found a wide range of metabolic equivalent (MET) values for yoga practices and poses between the 13 studies. MET values are a measure of how hard the body is working, and can be used to calculate calorie burn. According to American College of Sports Medicine (ACSM) guidelines, an exercise with a MET value less than 3 is considered light intensity. Moderate intensity is between 3 and 6, while vigorous is 6 METs and up.

In the studies included in Larson-Meyer’s review, MET values for full yoga sessions ranged from 2.0 to 7.4—suggesting that yoga can vary from very relaxed to quite vigorous. The study evaluating a Nintendo Wii Fit yoga practice reported the lowest value, while a group of experienced practitioners flowing quickly through four rounds of Sun Salutations (Surya Namaskar), a series of 12 poses commonly practiced in modern yoga classes, recorded the highest value.

The review found that

most individual yoga postures, when evaluated on their own, had MET values in the light-intensity category. The few that did reach moderate levels included Dandayamana-Janushirasana (Standing Head to Knee), Dandayamana-Dhanurasana (Standing Bow), Trikanasana (Triangle), and Tuladandasana (Balancing Stick). Inversions, such as Sirsasana (Head Stand) only received MET values up to 2.5—although the studies did not measure some of yoga’s most difficult poses, such as Bakasana (Crow) or Adho Mukha Vrksasana (Hand Stand).

Interestingly, the one study that looked at Bikram yoga did not find significantly higher energy expenditure than those found in studies of other yoga types. Bikram classes adhere to a set series of poses and instructors conduct them in 105-degree rooms. They often promote themselves as significant calorie burners due to the amount of sweat participants generate.

But the MET

values of Bikram “were within the same range as yoga practiced at room temperature,” Larson-Meyer wrote. Bikram does not incorporate Sun Salutations or flowing transitions from move to move, she points out, so it may require less energy than other styles. (If the sequences were exactly the same, a person may indeed burn more calories in a hotter room.)

“I know a lot of people who attend hot yoga and they feel like they get a better workout, and that’s great,” says Larson-Meyer. “But for people who might be uncomfortable in the heat, it’s good to know that’s not necessarily true—you can get a similar workout in a room at normal temperature.”

The bottom line, says Larson-Meyer, is that yoga can be whatever you want it to be: a relaxing, light-intensity stretch session or a full-on workout with plenty of high-intensity moments.

Choosing a restorative class

with more seated poses will likely give you the former, while one that incorporates lots of fast-paced transitions (jumping rather than stepping, for example) can give you the latter. Sessions that include standing poses and Sun Salutations are also likely to give you a greater burn.

“Most studies show that yoga is pretty comparable to walking,” says Larson-Meyer. “But if you truly desire to achieve a higher MET value, you can still accomplish it by performing specific, more challenging poses at a faster pace than your usual practice.”

Certain poses can count, in small amounts, toward the ACSM’s and American Heart Association’s recommendation to get at least 150 minutes of moderate exercise per week, she concludes. But if you’re just starting out or prefer a gentler style of yoga, a good portion of your practice may not be intense enough to meet those criteria.

That doesn’t mean

you shouldn’t practice this type of yoga, if that’s what you like. Larson-Meyer states that even light-intensity yoga has shown to boost strength, improve balance and flexibility, calm the mind, and reduce stress. It’s great cross-training for people who do more intense workouts on other days, and it may be a sustainable form of exercise for older adults or people with joint problems, rheumatoid arthritis, or back pain.

“The most important thing is that you’re doing it in a safe environment with a qualified instructor, and that you’re getting the benefits of centering and focusing on things other than the physical body,” she says. “Other than that, people should find a higher- or lower-intensity style that works for them and their fitness goals.”
