Jumping for Your Heart
Jumping jacks are a form of aerobic exercise. Your heart is challenged to pump harder to meet the increased oxygen demands of your muscles, according to a May 2011 article published online by Scientific American. As you do jumping jacks, your pulse increases and breathing is labored. These are signs that you are working your cardiovascular system. Incorporating jumping jacks into an exercise routine contributes to a stronger heart and more efficient cardiovascular system.
