Make sure you have a pair of shoes that have good support. Try walking a few blocks when you start out and slowly increase your distance. I like to walk on dirt, grass, mulch or sand so it's not so hard on my body. Concrete is the last thing you want to be walking on. Your hips, knees and legs take at least 2-3 times your weight with etch step you take. Take it slow and walk softly on your path. Hope this helps.
