# How Much Weight Can You Lose by doing crunches

### Weight Loss and Calorie Burn Calculator

Here you can find how much weight can you lose doing crunches, as well as learn how to calculate the calories spent and the equivalent weight loss.

## How to calculate the burned calories or weight (mass) loss

The number of calories you burn depends on:

- the physical activity
- the person's body weight
- the time spent doing the activity

Multiply your body weight in kg by the MET (Metabolic equivalent) value by the time of activity, you'll get the approximate energy expent in Kcal according to the person's body weight. In this case, doing crunches at a MET value, burns Kcal/kg x body weight/h.

A 70 kg individual doing crunches for 30 minutes will burn the following:

(METs x 70 kg body weight) x (30 min/60 min) = 98.0 Kcal.

is the value in METs for doing crunches.

To transform the value in calories into pounds just divide the value in calories by 3500. So,

98.0/3500 = 0.03 pound = 0.45 ounce = 12.7 grams of mass. We can't say that it is fat because it could be also muscle.
