You can choose from bicycling, aerobic dance, swimming, walking, and stepping. Your choice will be decided by your physical condition, your history, your interests and your goals. Switch between 2 or more types of aerobic exercises for an excellent workout. You can also alternate between high impact and low impact aerobics. High impact aerobics are harsh on your body and can cause injury. But when you alternate between the two types of aerobics, your chances of injury and overuse of specific muscles decrease.http://www.weightloz.com/category/Cardio-Exercise-at-Different-Intensities.html

16 huh... if you like to dance, I suggest turning your favorite music on and get with it. that should do you good. in all the areas you need. If your all alone you can try out all those moves you ve seen others do but never dared to try. Dancing makes if feel like your having fun instead of working out....
