30 minutes of HIIT burns 220–390 calories plus significant afterburn. Weight table and recovery strategies.
Thirty minutes of HIIT burns approximately 220–390 calories during the workout.
A 30-minute HIIT session is at the upper end of recommended HIIT duration. True high-intensity effort is difficult to maintain beyond 20–25 minutes, so 30-minute HIIT sessions typically include a warm-up, cooldown, and slightly longer rest periods between high-intensity intervals. This structure still delivers exceptional cardiovascular training and calorie burn while allowing adequate recovery between efforts.
It burns roughly 2.5 times more than walking for the same duration and 40–50% more than moderate cycling. Among 30-minute workout options, HIIT consistently ranks among the highest for total calorie impact.
Limit full HIIT sessions to 2–3 times per week to allow proper recovery. On alternate days, opt for lower-intensity activities like walking, yoga, or easy cycling.
Direct answer: 30 minutes of HIIT burns an estimated 266–468 calories, depending on body weight (180 lb / 82 kg: ~369 kcal). Intensity assumed: Typical HIIT session including rest intervals (MET 9). This is an estimate, not a measurement.
| Body weight | Calories burned |
|---|---|
| 130 lb (59 kg) | ~266 cal |
| 155 lb (70 kg) | ~315 cal |
| 180 lb (82 kg) | ~369 cal |
| 205 lb (93 kg) | ~419 cal |
| 230 lb (104 kg) | ~468 cal |
Example: At MET 9, a 180 lb (82 kg) person doing 30 minutes of HIIT burns approximately 369 calories: 9 × 82 × 0.50 h ≈ 369 kcal.
An estimated 266–468 calories, depending on body weight. A 180 lb (82 kg) person burns about 369 kcal, calculated as MET 9 × 82 kg × 0.50 hours.
About 12.3 kcal per minute for a 180 lb (82 kg) person, or 4.5 kcal per kilogram of body weight across the whole session.
Because the MET formula scales directly with body mass: a 130 lb person burns about 266 kcal here versus 468 kcal for a 230 lb person — a 76% spread for the identical session.
From the 2024 Adult Compendium of Physical Activities, the reference database of measured MET intensities for physical activities. Every figure on this page uses that value in the formula Calories = MET × body weight (kg) × duration (hours).
They are estimates from population averages, not measurements. Individual results commonly land within about ±15% of the figure shown; actual intensity and pace, body composition and fitness, terrain and technique all shift the real number. The values are gross calories, so they include the energy you would have burned at rest.
