If you think running and biking long distances will help your endurance read this article !!

The benefits of low level aerobic work (walking, hiking, cycling, swimming):
- increases capillary network (blood vessels that supply the muscle cells with fuel and oxygen)
- increases muscle mitochondria
- increases production of fat-burning and fat-transporting enzymes
- more fun, because you can talk with a partner while doing it

The benefits of interval training (sprinting in short intense bursts)
- increases muscle fiber strength
- increases aerobic capacity (work ability)
- increases muscle mitochondria (the main energy production center in muscle)
- increases insulin sensitivity
- increases natural growth hormone production

The costs of chronic (repetitious) mid- and high-level aerobic work
- requires large amounts of dietary carbohydrates (SUGAR)
- decreases efficient fat metabolism
- increases stress hormone cortisol
- increases systemic inflammation
- increases oxidative damage (free radical production)
- boring!
