The short answer
A single push-up burns roughly 0.3 to 0.6 kilocalories, depending on body weight and pace. 100 push-ups therefore cost about 30 to 60 kcal. If you count the whole session of about ten minutes including rests, you end up at 40 to 100 kcal – as much as an apple or half a chocolate bar. For weight loss, push-ups are still valuable, just for a different reason than most people think.
How to calculate your own burn
Exercise scientists estimate energy expenditure with the MET value (metabolic equivalent). One MET equals your resting metabolic rate, roughly one kilocalorie per kilogram of body weight per hour. The Compendium of Physical Activities, the standard reference table in research, classifies bodyweight strength exercises such as push-ups, sit-ups and pull-ups like this:
- light, with long rests: about 2.8 MET
- moderate, normal training: about 3.8 MET
- vigorous, short rests, circuits: about 8 MET
The formula is: kcal = MET × body weight in kg × duration in hours. For someone weighing 75 kg who trains moderately for ten minutes: 3.8 × 75 × 0.17 ≈ 48 kcal. In a vigorous circuit it is around 100 kcal over the same period.
Reference values for a ten-minute session
| Body weight | Moderate (3.8 MET) | Vigorous (8 MET) |
|---|---|---|
| 60 kg | approx. 38 kcal | approx. 80 kcal |
| 75 kg | approx. 48 kcal | approx. 100 kcal |
| 90 kg | approx. 57 kcal | approx. 120 kcal |
| 105 kg | approx. 67 kcal | approx. 140 kcal |
These are estimates, not measurements. Fitness watches and apps that convert individual push-ups into calories work with the same averages – the decimal places feign a precision that doesn't exist. The afterburn effect after training is real, too, but small: it usually makes up only a fraction of the burn during the session.
Why push-ups still matter for weight loss
You lose weight through a calorie deficit, and that is created mainly at the table: one kilogram of body fat equals about 7,000 kcal. No push-up session can compete with a few bites less. Strength training has a different job when losing weight – it decides what you lose.
- Preserve muscle: If you don't train in a deficit, you lose muscle along with fat. Studies repeatedly show that strength training in a calorie deficit protects lean mass far better than dieting alone. You get lighter, not just smaller.
- Support your resting metabolism: Muscle tissue burns energy even at rest, roughly 13 kcal per kilogram per day. That is no fat-burning turbo, but it slows the drop in energy expenditure that accompanies every diet.
- Shape and strength: With muscle preserved, the result looks firmer, and daily life, stairs and carrying get easier – a noticeable gain, especially at a higher starting weight.
How building muscle without weights works and when push-ups are enough is covered in the article Building Muscle with Push-ups.
More burn from the same time
If you still want to tune your session for calories, you have three levers:
- Shorter rests: 30 instead of 90 seconds between sets moves the session from the moderate into the vigorous range.
- Circuits instead of a single exercise: Push-ups alternating with squats, lunges and mountain climbers. The large leg muscles drive the burn more than the upper body alone.
- Add burpees: They combine a push-up and a jump and are among the most demanding exercises without equipment.
A simple twelve-minute circuit: 40 seconds of work, 20 seconds of rest, alternating push-ups, squats, mountain climbers and lunges, three rounds. If you like intervals, the article HIIT or Zone 2 has more on how such sessions combine sensibly with endurance training.
What really counts: a little every day
In weight loss, the hardest session doesn't win – the one you are still doing in week eight does. 50 push-ups a day add up to more than 18,000 repetitions over a year – a considerable training stimulus that secures muscle retention while your diet creates the deficit. People who see their streak are more likely to stick with it: that is what the article Why Daily Push-ups Change Your Life is about.
