Short answer: For many adults, 100 push-ups may burn roughly 30–60 calories, but this is only a broad estimate. The same 100 reps can take very different amounts of time and effort, so no single number is accurate for everyone.
Calorie questions look precise, but push-ups are difficult to measure in isolation. A person completing 100 continuous reps spends less time than someone using ten sets with long rests. Wearables and calculators also use generalized equations rather than direct measurement.
Why the estimate varies
- Body mass: moving a larger body generally requires more energy.
- Duration: total active time affects the estimate.
- Pace and range: controlled full-range reps differ from quick partials.
- Rest: long breaks change average intensity.
- Efficiency: trained people may perform the same work more economically.
A practical way to estimate
Time the complete session, including the work periods you want to count, then use a reputable activity estimate based on body weight and intensity. Treat the result as an approximate range. Avoid claiming that every push-up burns a fixed fraction of a calorie.
Better progress metrics
Track clean repetitions, sets, variation, range, rest time and weekly volume. These measurements respond directly to training. The push-up counter app guide explains which tracking features are useful.
- Strength endurance at a chosen variation
- Pacing across multiple sets
- Consistency over several weeks
- Technique under fatigue
Are push-ups good for fat loss?
Push-ups strengthen the upper body and can contribute to an active routine, but fat loss depends mostly on sustained energy balance. A balanced program with walking or cardio, full-body strength work, adequate sleep and appropriate nutrition matters more than the calorie estimate from one exercise.

Count progress—not imagined calories
RepSaga tracks completed push-ups and turns them into battles, achievements and streaks without promising a precise calorie number.
Frequently asked
Does 100 push-ups burn 100 calories?
For most people, no. A broad estimate is much lower, and actual energy use varies.
Can push-ups reduce belly fat?
No exercise selectively removes fat from one area. Push-ups can support fitness within a broader nutrition and activity plan.
