Deciding to take up a regular exercise program will not only help you lose weight but will benefit your overall health. Choosing a fitness regime should include a consultation with your doctor about what would be right for you individual case. If you have back problem or retinal problems, impact exercises are forbidden. Aerobics and heavy exercises with gym equipment too should not be done without consulting your doctor. Walking of course is an all-time best exercise program. Include it in your daily routine as much as possible.
