Lisa also says that, as with any exercise program, you should start slowly. "Try walking at a moderate pace for 15–20 minutes two or three times each week. As you feel stronger, pick up your pace and walk longer distances. You can add hills to your route to challenge yourself even further. Gradually work up to walking at a 15-minutes-per-mile pace for one hour four or five times each week. Be sure to take along a bottle of water and proper identification just in case!"
