How to Calculate Your Target
Cardiovascular training can be defined as your body’s ability to get oxygen and blood to the muscles. When you do physical activity your pulse will quicken and your breathing gets deeper, therefore you are using your cardiovascular system.
During cardiovascular exercise, your target heart rate should be between 55-85% of your maximum heart rate. Calculate your maximum heart rate by subtracting your age from 220 (i.e. 220 – 23 = 197). Multiply the result by 0.85 to calculate 85% of your maximum heart rate (i.e. 197 x 0.85 = 167.5). This is the high end of your training range, or the fastest that your heart should beat when you exercise.
