"Train hard and train often,” said Hirofumi Tanaka, a 41-year-old soccer player and exercise physiologist at the University of Texas.
Dr. Tanaka said he means doing things like regular interval training, repeatedly going all out, easing up, then going all out again. These workouts train your body to increase its oxygen consumption by allowing you to maintain an intense effort.
“One of the major determinants of endurance performance is oxygen consumption,” Dr. Tanaka said. “You have to make training as intense as you can.”

I hate those guys that eat saw dust and shit 2 by 4's. They are right, intensity is the the only way to train, that is why circuit training works so well. Take TN for example, her beer arm will put you out if one reaches the cooler before her

I've heard TN can out drink any man who doesn't cheat cabanaben
