How many calories do you burn?

How to calculate calories (burned)

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

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

So, a kg individual for minutes expends the following:

( METs x kg) x ( min/60 min) = Kcal.

Notes:

• is the value in METs for
• The time unit is expressed in minutes
• The mass (weight) unit is expressed in kilograms
