It might sound trivial, but it really helps you understand what’s going on with your body when you exercise if you know your heart rate. To get a sense of your resting heart rate and your maximum heart rate, take your pulse twice, before and after vigorous exercise. You can use two fingers against the base of your jaw to feel the pulse.
As you continue your training, check your pulse right after a strong aerobic workout. You will find that with time your pulse will decrease. This is a sign that your cardiovascular system is becoming stronger, and is capable of oxygenating your blood with less effort.
