How many calories do sit-ups burn? This free sit up calorie calculator estimates calories from your weight and the number of sit-ups (or time), including calories per rep.

Sit-ups are moderate calisthenics (~3.8 METs). With a rep count we estimate active time from your pace; for total time, switch to “Time”.

A rough estimate — sit-ups burn modestly because each rep is brief. Their main value is core strength, not calorie burn. Calorie use varies with body weight, tempo and form.
Use this free sit up calorie calculator to estimate how many calories your sit-ups burn. Enter your weight and the number of sit-ups (or the time spent) to see the estimate, plus calories per sit-up.
What this sit up calorie calculator shows you
A sit up calorie calculator estimates the energy your sit-ups use, based on your body weight, the number of reps (and pace) or time, and the activity’s intensity. Sit-ups are moderate calisthenics, around 3.8 METs, so the calorie total is modest.
How sit-up calories are calculated
Calories ≈ MET (3.8) × weight (kg) × active time (hours)
Active time ≈ reps ÷ pace (reps per minute)
A 70 kg person doing 50 sit-ups at a steady pace burns roughly 7 calories — about 0.15 kcal each. Over a continuous 5-minute set, that’s closer to 22 calories.

Do sit-ups burn belly fat?
Not directly — you can’t “spot reduce” fat from one area, and sit-ups burn few calories. They strengthen your core, which is valuable, but visible abs come mainly from overall body-fat levels, driven by total activity and diet.

Sit Up Calorie FAQ
How many calories do sit-ups burn?
Not many — about 0.15 calories per sit-up for a 70 kg person, so roughly 7 calories for 50. Each rep is brief, so even big sets total only a few minutes of work.
How many calories do 100 sit-ups burn?
Around 15 calories for a 70 kg person at a steady pace, a little more for heavier bodies or a slower tempo. Enter your details for a personal estimate.
Do sit-ups burn belly fat?
Not directly. You can't spot-reduce fat, and sit-ups burn few calories. They build core strength, but visible abs come from lower overall body fat, driven by total activity and diet.
How is sit-up calorie burn calculated?
Sit-ups are treated as moderate calisthenics (about 3.8 METs). Calories equal MET × weight in kg × active time, where active time comes from your rep count and pace, or the minutes you enter.
Are sit-ups good exercise?
They're useful for core strength as part of a balanced routine, though many people prefer planks and other moves too. For calorie burn, cardio does far more.
Is the sit up calorie calculator free?
Yes, this sit up calorie calculator is completely free, needs no sign-up, and gives instant results in your browser.
