### Results:

 Weight (fat and/or muscle) lost: (grams) Calories burned:
Someone weighing 70 Kg or 154.3 lb doing sit ups (vigorous effort) burns 186.7 calories in 20 minutes. This value is roughly equivalent to 0.05 pound or 0.85 ounce or 24.2 grams of mass (fat and/or muscle).

• Doing this activity 3 times a week for 20 minutes will burn 0.64 pounds or 0.29 Kg a month.
• Doing this activity 5 times a week for 20 minutes will burn 1.07 pounds or 0.48 Kg a month.

A person will loose 0.85 ounce or 24.2 grams and will burn 186.7 calories doing sit ups (vigorous effort) for 20 minutes

## 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 sit ups (vigorous effort) at a MET value, burns Kcal/kg x body weight/h.

A 70 kg individual doing sit ups (vigorous effort) for 20 minutes will burn the following:

(METs x 70 kg body weight) x (20 min/60 min) = 186.7 Kcal.

is the value in METs for doing sit ups (vigorous effort).

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

186.7/3500 = 0.05 pound = 0.85 ounce = 24.2 grams of mass. We can't say that it is fat because it could be also muscle.
