minutes

or

Typing an activity in the box below (Ex.: 'running').

### Results

grams
(fat and/or muscle)

Someone weighting 70 Kg or 154.3 lb doing crunches burns 98.0 calories in 30 minutes. This value is roughtly equivalent to 0.03 pound or 0.45 ounce or 12.7 grams of mass (fat and/or muscle).

• doing crunches 3 times a week for 30 minutes will burn 0.34 pound or 0.15 Kg a month.
• doing crunches 5 times a week for 30 minutes will burn 0.56 pound or 0.25 Kg a month.
• doing crunches every day for 30 minutes will burn 0.78 pound or 0.36 Kg a month.

By using the calories burned calculator, you just need to fill some data and get the value of calories burned in Kcal.

## How to calculate calories (burned)

The number of calories you burn while exercising is dependent on:

• the exercise you do
• the time spent doing the activity

By multiplying the body weight in kg by the MET (*) value and duration of activity, you can estimate the energy expenditure in Kcal specific to a persons body weight. In this example, doing crunches at a 2.8 MET value, burns 2.8 Kcal/kg x body weight/h.

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

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

2.8 is the value in METs for doing crunches.

(*) MET - Metabolic equivalent
