title: Ask the doctor.  I am a 68-year-old overweight woman with COPD who has recently started exercising regularly.  I have been riding stationary bike for about 10 minutes, six days a week, and I just can't seem to go longer without getting short of breath.  My doctor suggested that I stop using the bike and start weight training.  How will that help me get in shape and lose weight?
