Take Your Pulse
Check your pulse rate at the beginning and after sessions to see how this exercise strengthens your heart. To find the pulse rate you should be aiming for, subtract your age from 220 and multiply by 0.9 and 0.6. This gives you a high and low range. For example, a 25 year old needs to raise the pulse rate to the range 117 to 176 during exercise to improve their aerobic conditioning.
