recommendations made by the American Heart Association? Why or why not?
3. The average adult contains more than 5 liters of blood. The heart is continuously beating to keep the
blood circulating throughout the body. Heart rate is a parameter that describes how frequently the heart
beats. For most people, a resting heart rate between 60 and 100 beats per minutes is normal. To benefit
from physical activity, the heart rate needs to increase. Understanding how much to increase the heart rate
is critical before you begin an exercise. Visit the following site to review the heart rates that should be
targeted during exercise then complete the table below. -

4. Determine your resting heart rate by completing the following: Use your index and middle fingers of
one hand to feel your radial pulse on the opposite wrist. Your radial pulse will be on the "thumb side" of
your wrist, just below the base of your hand. While you are sitting still, measure the number of beats you
feel in your radial pulse for 10 seconds. Multiply this number of beats by six to get your resting heart rate
in beats per minute (bpm). Alternatively, you may be able to monitor this value more accurately using
your phone. Record your resting heart rate below.
