Calorie Burn: Yoga
Estimate calories burned in a yoga session from body weight, duration, and practice style.
What this tool does
This calculator estimates yoga energy expenditure using style-specific MET values from the 2024 Adult Compendium of Physical Activities. It multiplies body weight, session length, and the MET for the chosen practice: Nadisodhana and breath-centred practice at 2.0 METs (code 02170), Hatha at 2.3 METs (code 02150), Vinyasa at 2.7 METs (code 02185), Hot yoga at 3.0 METs (code 02155), and Power yoga at 4.0 METs (code 02160). Secondary rows show the MET applied and the net-of-resting figure, which for yoga is a large fraction of the story: gentle styles cost little more than quiet sitting.

How the yoga estimate works
The calculator applies the MET equation (MET × body mass (kg) × hours) with five published entries from the 2024 Adult Compendium of Physical Activities: Nadisodhana (alternate-nostril breathing and similarly still, breath-centred practice) at 2.0 METs (code 02170), Hatha yoga at 2.3 METs (code 02150), Vinyasa at 2.7 METs (code 02185), Hot yoga at 3.0 METs (code 02155), and Power yoga at 4.0 METs (code 02160), all listed in the Compendium's conditioning exercise category. The table also holds a high-intensity Hatha entry at 8.0 METs (code 02153) for unusually athletic sequences, mentioned here for context rather than offered as an option.
The formula, worked through
A 75 kg (165 lb) practitioner in a one-hour Hatha class: 2.3 × 75 × 1 = 172.5, rounded to 173 kcal. The net figure (energy above what an hour of sitting would have cost) is 98 kcal. That gap between gross and net matters more for yoga than for any cardio activity on this site, because the resting baseline is nearly half the total.
A second scenario: a vinyasa flow
A 65 kg (143 lb) practitioner in a 75-minute Power yoga class: 4.0 × 65 × 1.25 = 325 kcal. Continuous flowing sequences with frequent chaturanga transitions raise the per-minute cost about 75% above held-pose Hatha practice; a typical mixed vinyasa class, flowing in blocks with holds between, is priced by its own Compendium row at 2.7 METs. A 60-minute Nadisodhana or restorative-leaning session for a 75 kg person, by contrast, prices at 2.0 × 75 × 1 = 150 kcal gross, and only 75 kcal net.
Reading yoga numbers honestly
Yoga's published costs are low, and the honest framing is that calorie expenditure is not the primary measurable outcome of most practice. A systematic review by Larson-Meyer pooling 17 indirect-calorimetry studies found full yoga sessions averaging 2.9 METs once a single 7.4 MET sun-salutation outlier was excluded (comparable to slow walking), because much of a class is spent holding positions, transitioning slowly, or lying in savasana. Marketing claims of 400–600 kcal per hour for ordinary classes exceed the measured literature severalfold. Heated classes raise sweat loss dramatically, but sweat is water, not oxidised fuel; the Compendium's own Hot yoga entry sits at just 3.0 METs (code 02155), 0.7 above Hatha.
Where styles land
Within-class variation is wide. The Compendium prices continuous sun salutations (Surya Namaskar) at 3.5 METs (code 02180), though individual studies have measured them as high as 7.4; seated pranayama averaged 1.3 METs across the studies in the Larson-Meyer review. A class's average depends on its ratio of flow to stillness: truly continuous athletic flow belongs at the 4.0 Power entry, a typical mixed vinyasa class at the 2.7 Vinyasa row, and gentle and yin formats at or below the Hatha entry. Body weight scales the estimate linearly, and the load-bearing nature of arm-balance-heavy practice means heavier practitioners genuinely do work harder in absolute terms.
Gross versus net
At 2.3 METs, 43% of the gross figure is metabolism that would have run anyway. The net row ((MET − 1) × mass × hours) is therefore the more informative number for energy-balance arithmetic: 98 kcal for the worked Hatha hour. Activities in this range are better compared on their measured mobility, strength, and down-regulation outcomes than on their calorie lines.
Yoga in context
For calibration against familiar activities: an hour of Hatha at 2.3 METs costs about what 35 minutes of moderate walking costs; an hour of Power yoga at 4.0 METs slightly exceeds an hour of moderate-pace walking (3.8 METs) while falling short of brisk walking (4.8 METs). The comparison runs one way only (walking does not stretch hip capsules or train balance under fatigue) but it anchors expectations for anyone using this calculator alongside the site's walking and activity-comparison tools.

Questions
- Why is the yoga estimate so much lower than my fitness tracker's?
- Wrist trackers infer expenditure largely from heart rate, and yoga elevates heart rate for reasons other than metabolic cost: heat, inversion, breath manipulation, and isometric tension all push heart rate up without proportional oxygen consumption. Measured oxygen-uptake studies place ordinary Hatha classes at 2–3 METs. Consumer devices estimate energy poorly even on conventional exercise: a Stanford validation of seven wrist devices found median energy-expenditure errors of 27–93% depending on device, and yoga's uncoupled heart rate pushes the same machinery further astray.
- Does hot yoga burn substantially more calories?
- Measured energy cost rises only modestly in heated rooms: the Compendium's Hot yoga entry is 3.0 METs (code 02155) against 2.3 for Hatha. Profuse sweating reflects thermoregulation (water loss, not fuel oxidation), and scale weight lost in a heated class returns with rehydration. Studies comparing the same sequences at room temperature and in heat find similar oxygen consumption. The heated environment changes perceived exertion and flexibility far more than it changes the calorie line.
- Which entry fits a vinyasa flow class?
- The Compendium's Vinyasa row at 2.7 METs (code 02185) fits classes that flow for some blocks and hold or rest for others, which describes most studio vinyasa. The Power entry at 4.0 METs fits continuous flow with regular chaturanga-to-upward-dog transitions and little stillness. Continuous sun salutations are priced at 3.5 METs (code 02180), though individual studies have measured them as high as 7.4, so a rare class of mostly unbroken salutations can exceed the Power average.
- Is the gross or the net number the one to log?
- For energy-balance arithmetic, the net row. At Hatha intensity nearly half the gross figure is resting metabolism that would have occurred anyway; logging the gross 173 kcal alongside a resting-metabolism-based daily budget counts that hour's baseline twice. The net 98 kcal is the increment the practice actually added. For higher-MET activities the distinction shrinks, but at 2–4 METs it is material.
- Do arm balances and inversions change the cost?
- Briefly held strength postures raise instantaneous cost well above the class average, but they occupy little clock time in most sessions, so the hourly figure moves little. A practice deliberately built around repeated arm balances, handstand work, and continuous transitions behaves more like the Compendium's high-intensity Hatha entry at 8.0 METs (code 02153), an outlier value that describes athletic practice rather than typical classes.
Sources & Methodology
Calories = MET × body mass (kg) × duration (hours). MET values from the 2024 Adult Compendium of Physical Activities: Nadisodhana = 2.0 (code 02170); Hatha = 2.3 (02150); Vinyasa = 2.7 (02185); Hot = 3.0 (02155); Power = 4.0 (02160). The high-intensity Hatha entry = 8.0 (02153) and Surya Namaskar = 3.5 (02180) are referenced in the write-up but not offered as options. Net figure = (MET − 1) × mass × hours.
