Calories Burned Hot yoga at 55 kg — 220 kcal per Hour
Hot yoga at 55 kg (110–132 lb) burns about 220 kcal per hour. That figure comes from the activity's MET value of 4 in the 2011 Compendium of Physical Activities, multiplied by body weight: 4 × 55 kg × 1 hour = 220 kcal. This page works the numbers out in full — for 15, 30, 45, 60 and 90 minutes, across all four weight bands, and against four comparable activities at the same weight — so you can plan sessions with real figures instead of guessing.
Hot yoga is yoga practised in a heated room, typically 35–40°C, with classes that follow a set sequence of poses — often the 26-pose Bikram sequence or a heated Vinyasa flow. The heat makes you sweat heavily and the muscles feel looser, which is the attraction for many practitioners. At 4.0 METs — the Power yoga value, used here because the Compendium has no separate hot-yoga entry — it is a moderate activity, the same rating as Vinyasa yoga at room temperature: the heat adds sweat, not a higher MET value.
It suits experienced yoga practitioners who enjoy the heat and are comfortable with the intensity of a 60–90 minute class in a hot room. It is not a good first yoga class: learn the poses at room temperature first, and be honest about how you handle heat. The headline number to remember is the hourly figure at your weight — and the important context, explained below, that sweating more does not mean burning more. That is 220 kcal per hour at 55 kg, or about 110 kcal for a 30-minute session. Everything below is an estimate: MET values are population averages, and your own burn will vary with fitness, technique and conditions. That does not make the numbers useless — it makes them a planning tool, and a good one, as long as you treat them as approximate.
Calculate your own numbers
Use the Calorie calculator to work out your own burn for hot yoga at your exact weight and session length. Enter your weight, pick the activity and set the duration, and the tool applies the same MET formula shown below. You can also try the TDEE calculator to see how this session fits into your total daily energy use.

The formula, shown and cited
The standard way to estimate the energy cost of an activity is the MET formula from the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise, 2011; 43(8): 1575–1581):
Calories (kcal) = MET × body weight (kg) × duration (hours)
One MET is the energy you use sitting quietly at rest — about 1 kcal per kilogram of body weight per hour. An activity rated at 4 METs therefore uses 4 times as much energy as resting. The Compendium's MET values come from published studies that measured oxygen use during each activity, so they are measured averages, not guesses. The Compendium has no exact entry for hot yoga, so the data file uses the closest published value: yoga, Power, 4.0 METs.
Worked through for this page:
- MET for hot yoga: 4
- Body weight: 55 kg (the midpoint of the 50-60 kg band, 110–132 lb)
- Duration: 1 hour
- Calculation: 4 × 55 × 1 = 220 kcal
For a 30-minute session the same calculation is 4 × 55 × 0.5 = 110 kcal. Nothing else is hidden in the maths — if your weight or duration changes, only those two numbers change.
Your numbers at 55 kg
| Duration | Calculation | Calories burned |
|---|---|---|
| 15 minutes | 4 × 55 × 0.25 | 55 kcal |
| 30 minutes | 4 × 55 × 0.5 | 110 kcal |
| 45 minutes | 4 × 55 × 0.75 | 165 kcal |
| 60 minutes | 4 × 55 × 1 | 220 kcal |
| 90 minutes | 4 × 55 × 1.5 | 330 kcal |
That is about 3.7 kcal per minute of hot yoga at this weight. A short session still counts: even 15 minutes burns 55 kcal, and three 15-minute sessions across a day add up to the same 165 kcal as one 45-minute session.
How the burn changes with body weight
The MET value stays the same — it describes the activity, not the person — but the calorie total scales with weight, because a heavier body costs more energy to move:
| Body weight | Calories per hour | Calories per 30 minutes |
|---|---|---|
| 55 kg | 220 kcal | 110 kcal |
| 65 kg | 260 kcal | 130 kcal |
| 75 kg | 300 kcal | 150 kcal |
| 85 kg | 340 kcal | 170 kcal |
Two people doing the same activity for the same time can therefore burn quite different amounts, and that is expected — it is physics, not a mistake in the formula. If your weight sits between two rows, your figure sits between the two values.
At 55 kg (121 lb), the absolute numbers are the smallest of the four weight bands on this page, because a lighter body costs less energy to move. That does not mean the workout is easier — the effort, the heart rate and the relative intensity are the same as for a heavier person doing the same activity. What changes is only the calorie total, and that is exactly what the MET formula predicts: the same MET value multiplied by a smaller weight gives a smaller number. If your weight is near the bottom of the 50–60 kg band, the 55 kg figures are your best guide; if you are nearer 60 kg, your true figure sits a little above them.
How hot yoga compares
Here is hot yoga against four other activities at the same 55 kg, all using the same MET formula:
| Activity | MET | Calories per hour at 55 kg |
|---|---|---|
| hot yoga | 4 | 220 kcal |
| Vinyasa yoga | 4 | 220 kcal |
| cycling at a leisurely pace | 4 | 220 kcal |
| Nordic walking | 4.3 | 236 kcal |
| ballet | 5 | 275 kcal |
Use this table to choose, not to judge. A higher number means a harder session, not a better one: the activity you enjoy and repeat three times a week beats the activity that burns more per hour but that you quit after a fortnight. Mixing intensities across the week — one harder session, two easier ones — is usually more sustainable than doing the hardest activity every time.
Fitting hot yoga into your week
| Sessions per week | 30 minutes each | 60 minutes each |
|---|---|---|
| 2 sessions | 220 kcal | 440 kcal |
| 3 sessions | 330 kcal | 660 kcal |
| 5 sessions | 550 kcal | 1100 kcal |
At 4 METs, hot yoga counts as moderate activity, so it contributes directly towards the widely used adult target of 150 minutes of moderate activity a week. Three 30-minute sessions a week give you 90 of those minutes and burn about 330 kcal a week at 55 kg. Build up gradually — add 10% to your weekly total at most, and keep at least one rest day.
How to use the result
Hydrate before the class, bring water and a towel, and arrive early so your body can adjust to the room. Move at your own pace, rest in child's pose whenever you need to, and leave the room if you feel dizzy, nauseous or unwell — pushing through heat symptoms is never worth it. Eat lightly beforehand and rehydrate afterwards. Use the numbers on this page as a planning estimate: the calorie figure is the same as Vinyasa yoga, because the work is the same even though the sweat is not. If you are aiming to lose weight, keep the deficit modest at 300–500 kcal a day and keep total intake above the safety floors of 1,200 kcal a day for women and 1,500 kcal a day for men unless a healthcare professional advises otherwise.
What the number does NOT tell you
The MET formula measures the work of the poses, and the heat does not change that work — this is the most important limit on this page. Sweating heavily in a hot room feels like burning more, but sweat is water loss, not fat loss: the extra weight you lose in a class is fluid, and it comes back when you drink. The formula also does not account for the heat itself, which is a real physiological load: heart rate runs higher in the heat, and the risk of dehydration and heat illness is genuine, especially for people with heart conditions, low blood pressure or any other health concern. Check with a healthcare professional before hot yoga if any of that applies, and never practise hot yoga while ill or dehydrated.
Frequently asked questions
How many calories do I burn doing hot yoga for 30 minutes at 55 kg?
About 110 kcal. The maths is 4 METs × 55 kg × 0.5 hours = 110 kcal. That is an estimate from the Compendium average — your real burn depends on your fitness, your pace and the conditions. If you weigh more or less than 55 kg, use the weight table above to read your own figure.
Is hot yoga good for weight loss?
It can help, but only as part of an overall calorie deficit. At 55 kg, an hour of hot yoga burns about 220 kcal, which is a useful contribution — roughly the energy in a modest meal — but weight loss still comes from the total balance of food and activity across the week, not from one session. Aim for a gradual loss of 0.5–1% of body weight per week, and never drop below 1,200 kcal a day (women) or 1,500 kcal a day (men) without medical supervision.
How does hot yoga compare with Vinyasa yoga?
At 55 kg, hot yoga burns about 220 kcal per hour against 220 kcal for Vinyasa yoga — the two activities burn the same at this weight. The best choice is usually the one you will actually do several times a week — consistency matters more than a small difference in the hourly rate.
How accurate is the 4 MET value for hot yoga?
It is a population average from the 2011 Compendium of Physical Activities (Ainsworth et al.), which compiled measured energy costs across published studies. Individuals vary by roughly 10–20% around the average because of fitness, body composition, technique and conditions. Treat 220 kcal per hour as a planning estimate, not a precise measurement of your own body.
How many calories do I burn doing hot yoga in an hour at 55 kg?
About 220 kcal — the maths is 4 METs × 55 kg × 1 hour. That works out at about 3.7 kcal per minute. Over a week, three one-hour sessions would add up to about 660 kcal from this activity alone, before the rest of your daily movement.
Estimates only, not medical advice. Minimum safe intakes: 1,200 kcal/day women, 1,500 kcal/day men — consult a healthcare professional before a very-low-calorie diet.
