Age is but a number

As I've said many times before here on That's Fit, it's never too late to start exercising. Barring any doctor-issued mandate against doing so, performing even low-intensity workouts can greatly enhance your health at any age.

A recent study, published in the popular journal Hypertension, examined the effects of exercise on men in their 20s and men in their 60s. As expected, the older men started with more constricted blood vessels, increasing their risk for hypertension and heart attack. But, after only three months of averaging 5 hours per week worth of walking, the older guys' blood-vessel function resembled that of the guys in their 20s.

Walking as little as 30 minutes per day can have a very positive impact on your cardiovascular health, in addition to offering a myriad of other health benefits.
