The Ultimate Health Checklist

To realize your healthiest self—and live your best life—you absolutely have to do Step 9. Start exercising. One of the most important things you can do, Dr. Oz says, is start walking.

"We're designed to walk. We won't get hurt walking," Dr. Oz says. "You can't get out of it, any excuses."

Your goal is to get up to 10,000 steps a day, but Dr. Oz says it's okay to start by walking for 30 minutes a day. This will make for 3,000 steps. Get your steps in with a pedometer and simple changes like taking the stairs instead of the elevator.

"Societies that have 10,000 steps under their belt every day don't have much under their belt," Dr. Oz says. "It's one of the best ways to stay thin."
