the purpose of this activity is to gain understanding about what happens to your heart rate when you perform cardiovascular, muscular endurance, muscular strength, and flexibility exercises. Use your heart rate monitor, and record your heart rate before the activity, two to three times during the activity (record the average),and immediately after the activity. between each exercise, walk slowly and allow your heart to go below 125 if possible. if your heart rate is over 125 at the end of an exercise, record how long it takes to get below 125. if after three minutes your heart rate has not returned to below 125, go ahead with the next activity.
