1. Just take a walk
That’s it. Start with something you know you can accomplish: Go for a 30-minute walk after dinner. Don’t worry about speed; don’t worry about distance. Just walk. Go out 15 minutes, come back 15 minutes. If it’s not safe for you to walk at night where you live, do it on your lunch hour or some other time of day. What you want to do is create a habit. This is a very simple way to start training yourself to live differently. Ultimately, use these walks to segue into a more vigorous cardiovascular workout routine. This could be anything from more walking to running or working out on an elliptical trainer.
