Exercise is challenging enough, but when you have more than a few pounds to lose and mere walking is exhausting or painful, what do you do? Start by looking into non-weight-bearing activities that burn calories, put less stress on your joints and help improve flexibility, says The National Women’s Health Information Center. Try swimming, water workouts, bicycling and rowing. Don’t be hard on yourself, though, if you can’t do an activity the first time. Keep trying! Moving your body—even for a short time—can help make you healthier.
