It is very important to understand your metabolic rate in order to understand the best way to exercise for your body. The Resting Metabolic Rate (RMR) test measures the oxygen levels in the air you’re breathing to determine your metabolic rate. This analysis calculates the amount of calories you burn each day, and from that you can determine the amount you will need to gain -- or burn further -- to gain or lose weight and reach your goals. The VO2 test is the second test to determine metabolic rate. In this short exercise test your oxygen consumption will be measured throughout your activity at different levels to determine your target heart rate workout zones. With this analysis you will be able to determine the optimal exercise zones to achieve the best results for burning fat or increasing endurance. American Family Fitness is incredibly thankful for this technology, and we are very excited to be able to share it with our members.
