As we all age (I don’t think I’m the only one), exercise 
becomes an even more critical component of a healthy lifestyle. It’s important to find something we enjoy doing that we can stick with for the long haul. One option is race walking.
"When outdoors, it is sometimes difficult to walk fast enough to get to the necessary level of exertion," says Dr. Joseph Mercola. "Try race walking. Racewalk.com has an excellent section on teaching you how to do this. However, if you use a treadmill indoors you can easily increase the incline to improve the intensity of the walking."
