Keep these tips in mind so your ticker stays in tip-top shape:
Hit the Accelerator Alternating speeds throughout your walk or jog (also known as fartleking, which means "speed play" in Swedish) can help you reach your maximum heart rate during a workout and increase your endurance. Try alternating walking two minutes with skipping, marching or galloping for one minute.
Drink UpStudies indicate that drinking five or more glasses of water daily can help you lower your heart disease risk by up to 60 percent. But if you're working out for an hour, you need to replenish your fluids. Experts say for every hour of exercise we do, we should drink between 28 to 40 ounces of fluids.
Cool It When the weather heats up and it's hot and hazy outside, trade your outdoor walking routine for some laps on an indoor track or treadmill. The temperature change takes a toll on your heart and can even cut oxygen flow to your blood, which may lead to clots.
