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.
The second step is to build muscle by lifting weights for 30 minutes a week. You can lift a dumbbell, a gallon of milk or your toddler...just start lifting!
Now that you're on the right track, Dr. Oz says you have to work up a sweat for about an hour a week. "The number one predictor of how long you're going to live is how well you can exercise your heart," he says. "If you can push yourself to sweat for an hour a week, that's great. You can break it down into three little segments of 20 minutes each."
Finally, you have to stretch so that you don't get hurt. Dr. Oz likes to do yoga, but he says you can get the same benefits from stretches you learned in high school gym class.
