You don't need balls, mats and elastic bands to get a great workout. Dr. Oz says there are only four exercises that you'll ever need to know—and none require fancy machinery!
First, Dr. Oz suggests that people walk for at least 30 minutes each and every day. "Walking is the foundation for all other exercises because it increases your stamina and prepares your body for strength training," he says. You should strive to walk 10,000 steps a day.
