How Many Calories Do Common Exercises Burn?
Calorie burn depends on three things: what you do, how much you weigh, and how long you do it. The table below shows estimated calories burned during 30 minutes of common exercises, calculated using MET values from the 2011 Compendium of Physical Activities.
| Exercise | 150 lb / 68 kg (30 min) | 180 lb / 82 kg (30 min) | MET |
|---|---|---|---|
| Walking — moderate (3.0 mph) | 125 cal | 151 cal | 3.5 |
| Walking — brisk (3.5 mph) | 154 cal | 185 cal | 4.3 |
| Running (6 mph / 10 min mile) | 350 cal | 422 cal | 9.8 |
| Cycling — stationary, moderate | 243 cal | 293 cal | 6.8 |
| Swimming — freestyle, moderate | 250 cal | 301 cal | 7.0 |
| Weight training — moderate | 125 cal | 151 cal | 3.5 |
| Weight training — vigorous | 214 cal | 258 cal | 6.0 |
| HIIT / Circuit training | 286 cal | 344 cal | 8.0 |
| Jump rope — moderate pace | 421 cal | 508 cal | 11.8 |
| Rowing machine — moderate | 250 cal | 301 cal | 7.0 |
| Elliptical — moderate | 179 cal | 215 cal | 5.0 |
| Stair climber | 321 cal | 388 cal | 9.0 |
| Yoga — hatha | 89 cal | 108 cal | 2.5 |
| Bodyweight exercises | 136 cal | 164 cal | 3.8 |
| Standing — general | 64 cal | 77 cal | 1.8 |
Of all common exercises, jump rope burns the most calories per minute — at 11.8 MET, it requires nearly 12 times the energy of sitting still. Running at 6 mph comes second at 9.8 MET, followed by stair climbing at 9.0 MET.
To estimate calories burned per hour, double the 30-minute values above. Keep in mind that very few people maintain high-intensity activities like jump rope or fast running for a full hour — your actual hourly burn will depend on how long you can sustain that pace.
These numbers are estimates. Your actual calorie burn varies with age, fitness level, lean body mass, and workout intensity — which is why the calculator above asks for those details.
How Many Calories Does Weight Training Burn?
Moderate-effort weight training burns roughly 125–150 calories per 30 minutes for most people, depending on body weight. That is lower than running or cycling during the session itself — but the number is misleading on its own.
Resistance training creates a post-workout calorie burn that cardio does not match. This effect is called EPOC (excess post-exercise oxygen consumption), sometimes referred to as the “afterburn effect.” Your body continues consuming extra oxygen — and therefore extra calories — for hours after you finish lifting. A study published in the European Journal of Applied Physiology found that after a 31-minute heavy resistance session, participants’ metabolic rate remained elevated for up to 38 hours post-exercise.
How significant is this? According to the American Council on Exercise, heavy resistance exercise produces a greater EPOC response than aerobic cycling at the same intensity. The afterburn from a single strength session adds an estimated 6–15% to the total calories burned during the workout.
The type of exercise matters too. Compound lifts — squats, deadlifts, bench press, rows — recruit more muscle mass and burn more calories per minute than isolation exercises like bicep curls or leg extensions. If calorie burn is a priority during your weight training session, building your workouts around compound movements and structured programming will give you the highest return.
If you want to increase calorie burn further during resistance training, shorten your rest periods or use circuit-style formats. Circuit training at vigorous effort registers 8.0 MET — more than double the 3.5 MET of a moderate-paced weight session with standard rest.
How Many Calories Does Walking Burn?
Walking speed changes calorie burn more than most people expect. At 3.0 mph (a casual pace), a 150 lb person burns roughly 125 calories in 30 minutes. At 4.0 mph (a brisk pace), that jumps to about 179 calories — a 43% increase from simply walking faster.
Incline adds even more. Walking at 3.5 mph on a 5% treadmill incline (6.0 MET) burns around 214 calories in 30 minutes for a 150 lb person. That is roughly 40% more than the same speed on flat ground — making incline walking one of the most efficient low-impact calorie burners available.
For the common goal of 10,000 steps per day — that translates to approximately 400–500 calories depending on your pace, weight, and terrain. Faster steps on incline terrain burn meaningfully more than slow steps on a flat surface.
Even standing burns more than sitting. At 1.8 MET, standing quietly for 30 minutes uses roughly 64 calories for a 150 lb person — compared to about 50 calories from sitting. The difference is small per session, but across an 8-hour workday, choosing to stand for half of it can add 50–70 extra calories burned.
How Many Calories Does Running Burn?
Running is one of the highest calorie-burning exercises per minute for most people. At 6 mph (a 10-minute mile), a 150 lb person burns roughly 350 calories in 30 minutes. At 8 mph (a 7.5-minute mile), that increases to approximately 493 calories in the same time window.
On a treadmill specifically, the calorie display uses a similar MET-based formula but typically assumes a 155 lb person without adjusting for individual differences. If your weight differs from that baseline, the treadmill reading will be off. The calculator above accounts for your actual body weight, age, and fitness level for a more tailored estimate.
One practical consideration: running at higher speeds burns more calories per minute, but most people cannot sustain high speeds for long durations. A 30-minute jog at 5 mph (7.0 MET) burns roughly 250 calories — and most beginners can sustain that pace far longer than an 8 mph sprint. Total calorie burn for a workout depends on both intensity and duration, not just speed.
How Is Calorie Burn Calculated?
This calculator uses MET values — metabolic equivalents of task — to estimate your energy expenditure. MET is a standard unit used by the American College of Sports Medicine (ACSM) to express the energy cost of physical activity relative to rest.
One MET equals the energy your body uses while sitting quietly — roughly 3.5 milliliters of oxygen consumed (VO2) per kilogram of body weight per minute, or about 1 kilocalorie per kilogram per hour. An activity rated at 8.0 MET requires eight times that resting energy cost.
The formula:
Calories per minute = (MET × 3.5 × body weight in kg) ÷ 200
Multiply the per-minute result by your workout duration to get total calories burned.
The MET values used in this calculator come from the 2011 Compendium of Physical Activities, developed by Ainsworth et al. and published in Medicine & Science in Sports & Exercise. The Compendium catalogs the energy cost of over 800 activities and is the standard reference used in exercise science research worldwide. A 2024 update to the Compendium expanded the database further and introduced separate compendia for older adults and wheelchair users.
This calculator also factors in your age, biological sex, and fitness level — details that most competing calculators ignore. These variables adjust the baseline resting metabolic rate (RMR), because a 25-year-old and a 55-year-old burn calories at different rates even during the same exercise.
Other calorie estimation methods exist. The Harris-Benedict and Mifflin-St Jeor equations estimate your basal metabolic rate (BMR) — the total calories your body burns at complete rest over 24 hours — and are commonly used in TDEE calculators. Heart rate-based estimation, used by most fitness trackers, measures your actual pulse to infer oxygen consumption and calorie burn in real time. Each method has tradeoffs: MET-based calculations are consistent and research-standardized but rely on population averages. Heart rate-based tracking is more individualized but sensitive to device accuracy, caffeine, stress, and skin contact quality.
Your total daily energy expenditure (TDEE) combines your BMR with all activity throughout the day — not just structured exercise. For most people, exercise accounts for only 5–10% of total daily calorie burn. The majority comes from BMR (60–70%) and non-exercise movement like walking, fidgeting, and daily tasks.
Are Calorie Burn Calculators Accurate?
No calorie calculator is perfectly accurate — this one included. Every MET-based calculator estimates energy expenditure from population averages, not from your individual physiology.
The standard 1-MET baseline was derived from a single reference subject: a healthy 40-year-old male weighing 70 kg (154 lbs). If you differ significantly from that profile — in age, sex, body composition, or lean body mass — the estimate will shift. Research from the Compendium’s own team shows that standard MET values can underestimate the actual energy cost for people with higher BMI or older age, because their resting metabolic rate differs from the 3.5 ml/kg/min reference.
Fitness trackers and smartwatches have their own accuracy issues. A study from Stanford University School of Medicine, published in the Journal of Personalized Medicine, tested seven popular wrist-worn devices and found they overestimated calorie burn by 27% to 93% depending on the device and activity. Heart rate-based tracking is more responsive to real-time effort than MET tables, but factors like caffeine intake, ambient temperature, and even how tightly the band fits your wrist can skew the reading.
MET-based calculators like this one tend to be more consistent across activities than wearable sensors, but neither method captures individual metabolic variation. Use the number as a directional guide — not as an exact measurement. If you need precise data, indirect calorimetry (measuring actual oxygen consumption in a lab) is the gold standard.
Should You Eat Back Calories Burned During Exercise?
If your goal is fat loss — generally, no. Eating back every calorie your workout burns erases the calorie deficit (consuming fewer calories than your body uses) you created in the first place.
A more reliable approach: set your daily calorie intake based on your sedentary total daily energy expenditure (TDEE), then treat your workout calorie burn as additional deficit rather than permission to eat more. This avoids the common problem of overestimating exercise burn and underestimating food intake — both of which research consistently shows people do.
If your goal is muscle gain or performance, partial replacement after training makes sense — particularly protein within a couple of hours of resistance training. But that is a nutrition strategy, not a calorie-matching exercise.
The core principle: exercise supports fat loss, but nutrition drives it. A 300-calorie workout is undone by a single extra snack if you are not tracking your intake independently.
Frequently Asked Questions
How many calories should I burn per workout to lose weight?
A realistic target for most people is 200–400 calories per session, 4–5 days per week, combined with a moderate calorie deficit from food. The specific number matters far less than consistency over weeks and months.
What exercise burns the most calories?
Among common exercises, jump rope has the highest MET value at 11.8, followed by running at 8+ mph (13.8 MET) and squash (12.0 MET). However, the “best” calorie-burning exercise is the one you can sustain long enough to accumulate meaningful total burn. A 30-minute jog burns more total calories than 5 minutes of jump rope you had to stop because of fatigue.
Does sweating more mean I burned more calories?
No. Sweating is your body’s cooling response — not a calorie indicator. You can sweat heavily in a hot room doing nothing. Calorie burn is driven by exercise intensity and how much muscle you engage, not by how wet your shirt gets.
Do I burn more calories lifting heavy or doing more reps?
During the session, calorie burn is similar. Heavy loads with fewer reps (3–6 range) and lighter loads with more reps (12–20 range) produce comparable in-session energy expenditure. The difference is afterward — heavy compound lifts tend to produce greater EPOC, meaning your metabolism stays elevated longer post-workout.
How many calories do 10,000 steps burn?
Roughly 400–500 calories for an average adult, depending on your weight, walking speed, and terrain. A 180 lb person walking briskly on varied terrain will burn significantly more than a 130 lb person strolling on flat ground.
How many calories do I burn per day without exercise?
Your body burns calories around the clock just to stay alive — this is your basal metabolic rate (BMR). For most adults, BMR falls between 1,400 and 1,800 calories per day. Add daily movement like walking, cooking, and fidgeting (called NEAT — non-exercise activity thermogenesis), and most people burn 1,800–2,400 calories per day before any structured exercise.
Is running or weight training better for burning calories?
Running burns more calories per minute during the session. Weight training burns fewer during the workout but elevates your resting metabolic rate afterward through EPOC and builds muscle tissue that increases daily calorie burn over time. For overall body composition, combining both produces better results than either alone.
Why does my fitness tracker show different numbers than this calculator?
Fitness trackers estimate calorie burn from heart rate sensors and accelerometers, which are affected by wrist fit, skin tone, device calibration, and arm movement during exercise. MET-based calculators use standardized activity data from controlled research. Both are estimates — they use different methods, so the numbers will rarely match exactly.
