That's too complicated for me. My exercise program is:

Get completely winded at least once a day.

It won't make you Lance Armstrong, and it isn't a weight loss program. However, it'll do subtle things like encourage you to take the stairs- and RUN up them. This kind of attitude gently pushes you towards a healthier overall lifestyle, while keeping your lungs and heart at a basic level of functionality. That's all I'm really looking for.
