What use is it to have a strong body, and a weak pump? I constantly hear guys talking about how they get out of breath walking to their cars, or up stairs, hmmmmm..........I wonder why.
If your going to take care of your body, take care of the whole package, not just the exterior. What good is a car with a great body, but the engine is shot? Find something that you enjoy, and do that, it dosnt have to be a treadmill, go out and take a walk in the woods, go hiking, play basketball..............just do it.
