Calories burned
tai chi

176 kcal / hour Tai chi burns approximately 176 calories per hour for a 70 kg (154 lb) adult, and 88 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 126 to 302 kcal.

It carries a MET value of 2.4 in the 2024 Adult Compendium of Physical Activities, which lists 2 measured variations of this activity from MET 1.5 to 3.3.

Calories burned tai chi by body weight

Energy cost scales with the mass you move, so body weight changes the answer more than anything else.

Every official intensity of tai chi

The Compendium lists 2 separate tai chi entries, each with its own measured MET value — from 1.5 to 3.3. Most calculators collapse all of this into one number. Pick the row that matches what you actually did.

Codes are 2024 Adult Compendium activity codes. A dash means the code could not be read unambiguously from the published table, so it is left blank rather than guessed — the MET value and description are unaffected.

What 176 calories an hour actually means

At MET 2.4, tai chi counts as light activity — it uses about 2.4 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 3 kcal per minute, or 176 kcal across a full hour.

Within sports, that ranks 85th of 91 activities by energy cost, a little below hairstyling (MET 2.5) and above grooming (MET 2).

Put differently: one hour of tai chi costs about the same energy as 36 minutes of ordinary walking.

On the food side, a chocolate bar (about 235 kcal) takes roughly 80 minutes of tai chi to offset at that body weight. That framing is useful for scale, but it is worth saying plainly: exercise and diet are not a ledger that cancels neatly, and appetite tends to rise with activity.

Questions

How many calories does tai chi burn per hour?

About 176 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 2.4. A 90 kg adult burns closer to 227 kcal in the same hour, because energy cost scales almost directly with body mass.

How many calories does 30 minutes of tai chi burn?

Roughly 88 kcal at 70 kg, 76 kcal at 60 kg and 126 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.

What is the MET value of tai chi?

2.4, taken as the median of the 2 tai chi entries in the 2024 Adult Compendium, which range from 1.5 to 3.3 depending on intensity. One MET is the energy you use sitting quietly, so MET 2.4 means 2.4 times that rate.

Is this an exact number of calories?

No, and no calculator can give you one. MET values are population averages measured in laboratory conditions; your own figure varies with fitness, technique, terrain, temperature and body composition. Treat these numbers as a solid estimate for planning, not a precise measurement — and treat any device or site claiming three-digit precision with suspicion.

MET value from the 2024 Adult Compendium of Physical Activities (activity code 15672). Calories computed as MET × 3.5 × weight kg ÷ 200 per minute. General information only — not medical, fitness or nutrition advice. Calorie figures are population estimates and vary between individuals.
