Meet the Strong Men and Women who go beyond mere fitness to pursue major muscle mass--from ancient Greeks, to performers in the 1800s astounding audiences with feats of strength, to the body builders of California's Muscle Beach! Lou Ferrigno and other stars share stories of the pursuit of muscle. Also looks at the effect of steroids.

Traces physical fitness' role in the health of the individual and society. From ancient Greek gymnasiums, where pupils pumped up the mind as well as body, to 19th-century Muscular Christians, who saw exercise as an obligation to God. Meet fitness gurus and fitness trainers, and test the latest, and earliest exercise equipment.

To run faster, jump higher, and play longer--the ultimate goal of all athletes. But when training runs its course, science and technology jump in. Explore the history and technological advances in everything from athletic shoes to football gear. And leap into a future filled with radar-enhanced baseballs and virtual-reality stadiums.

From professional sports to the playground, balls have been a way of life for generations. We will explore the research, development, technology and performance of balls.

In 1941, penicillin was first used to save human life. But now, bacteria has emerged resistant to every known antibiotic, and scientists have begun to fear that the era of the wonder drugs is near to its end.

When "poliomyelitis" swept the nation, thousands died or were disabled before American ingenuity, trial and error, and blatant acts of desperation led to one of the greatest scientific breakthroughs in history. We'll see how polio shaped the vision of FDR, and catapulted the young unknown doctor Jonas Salk to international celebrity.

In a historic survey of man's adaptation to killer environmental conditions, we travel to the desert, the Arctic, the sea, jungle, and space, charting the body's physiological responses to extreme circumstances such as frostbite, heatstroke, and hypothermia. We talk with military survival experts and learn about the latest cutting-edge survival gear, as well as the equipment aboard the space station, and look to the future, when nano-technology will create a new type of technology.

Do normal humans actually possess the ability to have super powers? In Utah, see how a man can strap on an exoskeleton and lift hundreds of pounds with virtually no effort. In England, visit "Mr. Cyborg," a man with the ability to control machines with merely a thought. In California, see a man glide through the sky like Superman, then it's off to Atlanta, Georgia to see how engineers have found a way to help people glide through the water like Aquaman. Learn how scientists at the University of Texas are building artificial muscles that are 400 times stronger than our own, and in Las Vegas, strap on velocity motion stilts for a little bionic high jumping and high speed running.
