Do you know you need to do exercise, but hate to do it because it is too uncomfortable? Why not exercise while you rest? Does it sounds too good to be true? Interval training allows you to exercise but in a more restful pace. With interval training you exercise up to a predetermined maximum heart rate, then slow down and rest at a slower exercise intensity. Your heartbeat will drop slowly to a level that is more restful. When your heart rate reaches the predetermined lower limit, you speed up again to bring your pulse back up. In this way you exercise hard, but in intervals. Both the upper and lower limits of your heartbeat are within the cardiovascular training range. This is much more comfortable than exercising without paying attention to your pulse rate, which is often near the max the entire time you exercise. Read up on interval training. It’s more fun to exercise when exercise is comfortable.
