Ask the Trainer: "What is RMR and Why Should I Care?"

Sep 18, 2018

Christian Agudelo, ACSM - CPT

The rate your body burns energy can be measured by calculating your RMR or Resting Metabolic Rate. Normal activity that isn’t associated with exercise but still burns calories are measured using your RMR. These numbers are then used to help calculate a healthy calorie goal needed to meet certain criteria such as weight loss or muscle gain, or if you are just looking to maintain. Many factors are considered when determining you RMR such as age, sex, height and weight and fat free body mass. All of these factors play a key role in increasing or decreasing RMR.

Earvin Bahena, NSCA - CSCS

Resting Metabolic Rate (RMR) is the rate at which your body burns energy. Your body uses a certain amount of calories to do normal functions like breathing and sleeping. Your age, sex and free muscle mass can alter what your starting rate is. This number is important because you can use it to find out how many calories you need to consume to gain, lose or maintain weight. You add your daily active calories(the calories you burn when you workout or by doing daily activities) to your RMR and that is how you can calculate your caloric goal to help you.

Spencer O'Neil, NASM- CPT

Your RMR is essentially the energy cost of your body at state of complete rest. It is also commonly known as your basal metabolism. Everybody has a rate that is unique to them because certain factors affect your metabolic rate. People with much more size and mass require larger amounts of energy to run. Age is huge factor on determining how many calories your body is burning at rest. Using the Harris-Benedict Equation you are able to calculate your RMR and it’s something that I encourage my clients to know especially when they are dieting. It’s important to know the appropriate caloric range to avoid running too low on energy.
