Determining your Target Heart Rate

In general, to see improvement, your heart rate should increase to a specific level, or range of beats per minute during your activity. The levels differ depending on your age. The traditional way to find your target heart rate is to subtract your age from 220 and then multiply the result by 0.6 (for the lower limit) and 0.9 (for the upper limit).
