1. Monitoring Your Heart Rate

2. Resting heart rate is the number of times your heart beats per minute when you are relaxing.
In general, a lower heart rate means a healthier heart. When you work out, however, you want to get your heart pumping faster. Your goal should be to reach your target heart rate.
Target heart rate is the number of heartbeats per minute you should aim for to help your circulatory system the most during exercise.

3. Maximum heart rate is 220 – your age.
Target heart rate is (220 - your age) x 0.5 = bottom of target heart range
(220 – your age) x 0.85 = top of target heart range.
