How Many Calories Can You Burn In Bikram Yoga? | Sweat Math

Calories Burned In Bikram Yoga Per 90-Minute Class

The class happens in heat, but the calorie math still comes from intensity and body weight. Exercise science uses “METs” to express how hard an activity is. One MET equals resting energy use; an activity at 3 METs burns three times resting energy. The formula is simple: calories ≈ MET × weight (kg) × hours. You can scan a plain explanation of METs on the CDC’s intensity page.

In the 2024 Adult Compendium, “Yoga, Hot” sits near 3.0 METs, while “Yoga, Power” is listed at 4.0 METs. A sun-salutation-heavy flow sits around 3.5 METs. That’s why two people can leave the same room with very different totals. Heavier bodies burn more per minute; faster flows add up too. A laboratory study from Colorado State measured averages around 330 kcal (women) and 460 kcal (men) for a 90-minute heated sequence, which lines up with a MET between 3.0 and 3.5 for common body weights.

Quick Estimates By Weight And Class Length

Use the table to size your session. These estimates lean on the Compendium’s 3.0 MET value for heated classes. If your studio leans “power,” your total trends toward the higher band.

Body Weight (kg / lb)	60-Minute Class (kcal)	90-Minute Class (kcal)
50 / 110	150	225
60 / 132	180	270
70 / 154	210	315
80 / 176	240	360
90 / 198	270	405
100 / 220	300	450

Once you’ve sized the burn, snacks and meals fit better once you set your daily calorie needs. That frame stops the “I earned it” swings that wipe out a week of smart choices.

Why Heat Doesn’t Magically Double The Burn

Heat changes how the session feels. Heart rate climbs, sweat pours, and the room asks more of you. Still, the calorie math follows the same rule set. MET is tied to the actual work your muscles do, not the thermostat alone. The Compendium lists a specific entry for heated yoga at 3.0 METs and a separate entry for power-style practice at 4.0 METs. That split is a handy way to frame expectations in any studio style.

The CSU team measured metabolic rate during the full series. Their averages match what the MET tables predict for common body sizes over 90 minutes. In short, it feels intense because heat strains thermoregulation, but the calorie total looks closer to brisk walking than to a spin race.

Method, Assumptions, And How To Personalize

The Formula In One Line

Calories burned ≈ MET × weight (kg) × time (hours). You can plug in 3.0 for heated classes, 3.3 for a salutation-heavy flow, or 4.0 for power.

Pick The Right MET For Your Class

• Heated, steady sequence: use 3.0.
• Heat with lots of flowing sun salutations: try 3.3–3.5.
• Heated power flow: use 4.0.

Adjust For Body Size And Time

Heavier bodies burn more per minute at the same MET. Longer classes scale linearly. A 75-minute session is 1.25 × the 60-minute line.

Close Variation: Calories Burned In Bikram Yoga Per Class Length

Studios often offer shortened formats. Use these simple ranges to plan around your day:

• 60 minutes: ~180–360 kcal for most, rising with body size and pace.
• 75 minutes: ~225–450 kcal.
• 90 minutes: ~270–540 kcal.

Ways To Nudge The Number Up Or Down

Range, Pace, And Rest

Deeper bends and steadier transitions add work. Longer holds push muscles past comfort and mildly raise energy cost. Extra rest, long sips, or slipping into child’s pose trims the total. That’s not a loss—heat management matters.

Breathing And Bracing

Controlled breathing keeps form tight. A tidy brace during standing series creates more muscular demand than a loose sway. You’ll feel it most in legs and trunk.

Room Factors You Don’t Control

Temperature and humidity vary by studio. Warmer, wetter rooms feel harder, yet the math still hangs on the poses and pace. Let the feel guide your effort, not the thermostat reading.

Hydration, Electrolytes, And Safety In The Heat

Sweat loss can be large. Bring a bottle, add sodium when sessions stack up, and sip before thirst runs away from you. If you’re new to heated rooms, start near a vent, ease range on your first visits, and take breaks. Heat stress, cramps, and dizziness are signals to pause.

Real-World Benchmarks

Numbers stick better when compared to everyday moves:

• Brisk walk at 3.5 mph: totals often land near a heated class of the same length.
• Power yoga: pushes above many heated steady-pace sessions for the same body weight.
• Elliptical, moderate: usually burns more per minute than a steady heated sequence.

Worked Examples You Can Copy

Example A: 60 kg Person, Standard 90

3.0 MET × 60 kg × 1.5 h ≈ 270 kcal. Add a faster flow (3.5 MET) and it’s ≈ 315 kcal.

Example B: 80 kg Person, Power-Style 75

4.0 MET × 80 kg × 1.25 h ≈ 400 kcal.

Example C: 90 kg Person, Standard 60

3.0 MET × 90 kg × 1.0 h ≈ 270 kcal.

How This Compares To Lab Data

The CSU measurements—about 330 kcal for women and 460 kcal for men over 90 minutes—sit right between the 3.0 and 3.5 MET lines for typical adult body sizes. That’s a helpful gut check when your tracker over-reads after a steamy class.

Calories By MET Choice (90-Minute Class)

Pick the row closest to your body weight; then choose the column that reflects class intensity.

Body Weight (kg)	3.0 MET (kcal)	4.0 MET (kcal)
60	270	360
70	315	420
80	360	480
90	405	540

Make The Burn Count Without Overdoing It

Fuel Light, Sip Often

A small carb-leaning snack an hour before class lands well for most. Add a pinch of salt to your bottle when classes cluster in a week. That helps you stay steady from standing series to spine work.

Respect Signals

Dizziness, pounding headache, or nausea are stop signs. Step out, cool down, and rejoin only if you feel normal again. New students, pregnant people, and anyone with heat sensitivity should talk with their instructor about cooler spots in the room or a shorter session.

Stack With Walking Days

Flexibility improves fast with consistent practice. Pair heated sessions with light walking on off days to keep total weekly burn steady without beating up joints.

Where These Numbers Come From

Two inputs drive the estimates used here. First, the Compendium’s category entries list “Yoga, Hot” near 3.0 METs and “Yoga, Power” near 4.0 METs; a salutation-heavy format sits around 3.5. Second, direct measurements from a university lab land in the same neighborhood for a full heated sequence. You can read the MET definition in plain terms on the CDC page on intensity and skim the current Adult Compendium tables for the exact entries.

Bottom Line For Your Training Week

Heated classes burn a tidy amount, build balance, and can slot next to strength and cardio. Match the MET to your class style, size the total with the quick formula, and aim for steady weekly movement. If you want a simple movement boost on non-studio days, a short daily walk pairs well with mat time—our take on walking for health runs through an easy plan.
