If you haven't exercised in a while, a walk is a good place to start.

Here are a few tips to get the most out of your walk:

• Be aware of your posture. Keep your back straight, but not stiff. 
• Let your arms swing freely.
• Choose shoes with good arch support.
• Set a schedule and stick to it as much as you can.
• Plan your route and you can eventually change it if it no longer motivates you after a while.

FYI - I LOVE walking. My legs are so much stronger for all the walking I do.
