Training for a marathon can be no easy feat. Try setting small goals to achieve each week that eventually lead up to being able to run or walk a 5k marathon. For some, walking that distance takes little effort, but for others it can feel like climbing Mount Everest. Take small walks or runs each day and push yourself to make it further and further each week.

Try a few situps, and other exercises that encourage a full range of motion. These kinds of exercises keep your body flexible, which becomes important as you get older and want to be able to reach things you drop on the floor. Just make sure that you don't have your ankles bound when you do those sit-ups, though!
