Centuries before Viagra, the Taiwanese developed an ancient way of boosting a man's sexual prowess. All that's required is a willingness to lift weights.

Yin Diao Gong is an ancient form of medicine based on the mystical life force, Qi [Chi]. This rests in the loins and can be harnessed by lifting weights with the penis. Seasoned practitioners can lift up to 200 kg. [440 lb] "I become erect as soon as the Qi starts flowing through my body," says disciple. "I don't feel uncomfortable at all. I don't feel much. The Qi does the lifting."
