What is the best form of exercise? Walking or Jogging?

Like diets, exercise trends come and go. From Zumba classes to CrossFit, it seems like there are endless types workouts tailored for different levels of physical ability. But are these workouts really helping you get healthy or are they just all hype?

And which kind is the best for overall health? When it comes to the best form of exercise, experts say good old-fashion walking is the best. "Walking is a superfood.

It's the defining movement of a human," says Katy Bowman, a biomechanist based in Ventura, California. "It's a lot easier to get movement than it is to get exercise." While other forms of exercise build endurance and burn fat, these health benefits mean nothing if people are sedentary before and after a workout.

"Actively sedentary is a new category of people who are fit for one hour but sitting around the rest of the day," Bowman says. "You can't offset 10 hours of stillness with one hour of exercise." Instead, Bowman suggests in her book, Move Your DNA: Restore Your Health Through Natural Movement, that walking is type of movement the body needs and therefore, is the best form of exercise for cardiovascular heath and overall wellness.

A study last year by the University of Texas School of Public Health found that many people who view themselves as "active" fall into the actively sedentary category in reality. Researchers surveyed 218 marathoners and half marathoners to collect data about their training and sitting times.
