You will measure your pulse during three different activities. First, measure your pulse at rest and then while doing two activities of your choice. For the best variety, choose a moderately intense activity such as walking, followed by a more strenuous activity such as jogging or aerobics. Choose activities that you can sustain for 10 minutes. These activities can be performed indoors or outdoors. If you have limited space, you can perform the activities in place. Write down your two activity choices.
