Set a goal for physical activity that works within your lifestyle. You don't have to do long, intense workouts every day! Getting in your 10,000 steps a day is perfect. NSCA-certified personal trainer Laura Arndt said in a previous interview that if you take a 30-minute brisk walk, it's about 3,000 and 5,000 steps, depending on your speed and your gait. But don't sit the remainder of the day. The goal is to achieve another 5,000 steps through everyday activity. If you make it a habit to walk once during the day and once after dinner, you'll be able to get in your daily steps.
