Angela Spence  You have your runners on, your FitBit is charged, but now what?
When you exercise, your heart and breathing rates increase, delivering greater quantities of oxygen from the lungs to the blood, then to exercising muscles. Determining an optimal heart rate for exercise depends on your exercise goal, age, and current fitness level. Heart rate and exercise intensity share a direct, linear relationship: the more intense the exercise, the higher the heart rate. When you exercise at the highest possible intensity, your heart will reach maximal heart rate (HRmax), the fastest rate it is capable of beating. But exercising at a maximal heart rate (HRmax) for every exercise session will not produce efficient fitness results. These high intensities can rarely be sustained, negating the potential benefit of the exercise. Anna Kelsey-Sugg and Amanda Smith  If you can play Chopsticks on the piano, dance the Nutbush or ride a bike, chances are you've experienced muscle memory.
