For beginners who are concerned about their motivation or ability to walk far, I recommend the "five minutes out, five minutes back" plan. Just like it sounds, you walk out for five minutes, turn around, and walk back. If you feel ambitious, you can start with 10 minutes out, 10 minutes back, and off you go about your day! Increase by two to three minutes per week and before you know it you'll be up to 30 minutes. It sounds too simple to be true, but this is a realistic and achievable way to get started, and if you follow it, you'll be walking plenty before you know it.
