Resting Metabolic Rate (RMR) is the number of calories your body uses everyday to perform all its automatic functions. It is the main contributing factor of your total daily energy expenditure (around 70%). This makes calculating RMR a key step in determining how much you need to exercise or eat in order to achieve your weight goals. To get your BMR, simply download this app, enter your details and hit "Calculate". The app saves your details on your device so you don't have to enter them again & again. The app also makes it easy to share your RMR with others e.g. your personal trainer.
