So I'm not healthy unless I do cardio?
That's comical.
Jim Fixx basically started the jogging craze in the late 70's. He died of a heart attack (while jogging) at 52 years old.
For every Jim Fixx that dies cardio prevents a massive amount of heart attacks. The first thing they do for heart attack rehab is cardio exercise. If bodybuilders could show off their heart muscle at the club they would be doing a lot of cardio. Heart attacks are the number one killer of man.
1. Cardio lowers the resting heart rate showing the heart muscle is stronger and more efficient.
2. Cardio can lower blood pressure.
3. It raises HDl's lowering the risk of the number one cause of death.
4. It lowers blood fat in the form of triglycerides.
5. Cardio increases capillaries around the heart.
6. It can lower blood sugar.
7. It lowers visceral fat that leads to metabolic diseases.
I could go on. I view cardio as the gas tank and training for strength, power and muscular endurance is the engine. One is not good with out the other.
