How Often and How Long to Practice: What Trials Used

The honest answer first

Proper evidence not found for a single best number of days or minutes for yoga. We searched PubMed for dose-response and frequency reviews of yoga, and for trials of 10-minute and short daily yoga. We found trials that each used one schedule, and one trial that compared two schedules. This page reports what those studies used. It is not a prescription, and the schedules below came from studies of specific groups, often people with chronic low back pain. Ask your clinician what suits you.

What trials scheduled

Take-away: the best-studied pattern is roughly one class a week for about 12 weeks, often with home practice. The one trial that compared once versus twice weekly found no difference in back pain and function after 12 weeks in that group. [3] That does not show that more is never better for other goals or people.

Low back pain evidence overall

A Cochrane review of 21 trials (2,223 people) found small, clinically unimportant improvements in back function and pain versus no exercise, and all trials were at high risk of bias from lack of blinding, because people know when they are doing yoga. [7] See yoga for low back pain.

Weight programs and longer sessions

NCCIH describes a 2013 review of 17 yoga-based weight-control programs. It says the programs with the best results included longer and more frequent sessions (at least 75 to 90 minutes, at least 3 times per week), a longer overall program (3 months or more) and home practice, among other elements. [8] That comes from comparing programs, not from a trial that assigned people to different doses, and it applies to weight programs only. See yoga for weight loss.

How yoga counts toward general activity guidelines

The UK's NHS says adults should aim for at least 150 minutes of moderate activity a week, or 75 minutes of vigorous activity, and strengthening activities for all major muscle groups on at least 2 days a week. [9] It lists yoga, pilates and tai chi among muscle-strengthening activities. [9] It also says to talk to a GP first if you have not exercised for some time or have medical conditions. [9] Yoga varies from restful to sweaty, so how much it counts depends on the style; see is yoga exercise.

What about 10 minutes a day or every day?

A yoga therapist quoted by Cleveland Clinic says a little yoga every day, even 10 minutes, is better than once every few weeks. [10] That is practitioner opinion about building a habit. Proper evidence not found in the studies we searched for a trial of 10-minute sessions. We also found no study comparing daily with less frequent practice for injury risk, so we cannot say whether daily practice is safer or riskier. NCCIH notes that the most common injuries are sprains and strains. [8]

Practical points from the sources

• Adding more time or intensity is not covered by a tested rule. Cleveland Clinic's home-practice article says not to push beyond your limits and to treat joint pain as a red flag. [11]
• Starting with a beginner class is common advice; see yoga for beginners.
• If you have pain, a medical condition, or are pregnant or older, check with a clinician about frequency. [8] See who should check with a clinician before yoga.
