A heart rate monitor is an accurate tool for measuring these changes. According to cardiovascular expert Sally Edwards of Sacramento, California, author of The Heart Rate Monitor Guidebook to Heart Zone Training (Heart Zones Publishing 2010), “You only need two pieces of gear to work out: a good pair of athletic shoes and a heart rate monitor.”
