WorkOut Calories at Mac App Store analyse

This app helps you to calculate calories burnt during workouts.

This app is based on :-

1)The Resting Metabolic Rate (RMR) is the amount of energy required to maintain the bodys normal metabolic activity, such as respiration, maintenance of body temperature (thermogenesis), and digestion. Specifically, it is the amount of energy required at rest with no additional activity. The energy consumed is sufficient only for the functioning of the vital organs such as the heart, lungs, nervous system, kidneys, liver, intestine, sex organs, muscles, and skin.
The Harris–Benedict equations revised by Mifflin and St Jeor in 1990
males:-
(RMR) kcal/day = (9.99 x weight (kg)) + (6.25 x height (cm)) - (4.92 x age(years)) + 5; 

females :-
(RMR) kcal/day = (9.99 x weight(kg)) + (6.25 x height (cm)) - (4.92 x age (years)) - 161. 

2)MET:-A MET is the ratio of the work metabolic rate to the resting metabolic rate. One MET is defined as 1 kcal/kg/hour and is roughly equivalent to the energy cost of sitting quietly. For example: the energy cost of playing rugby is 8.3 METS, which means you use 8.3 times more energy than if you were to sit quietly and rest.

Calories Burnt = RMR x MET x duration in minutes / 1440.
