Exercises to increase the size of the penis and other parts of the human body have been around in one form or another since ancient times. Primitive tribes are still using weights, various objects and exercises to force parts of the human body to change size and achieve a new look. The women of the Paduang tribe use metal rings to lengthen their necks, while the people from other tribes hang heavy objects from their lips or ears. Chinese women of high birth had their feet shrunk in order to fit the local ideal of a beautiful look. Various penis enlarging techniques have been reported from nomad Arabic tribes. Body enhancement exercises performed by males were usually tied to the position of the person in question within the tribe or with the manhood initiation rites. It seems that men found early on that the human body can be modified using devices or exercises. The only traction devices at their disposal for a long period of time were weights, but stretching the penis using one’s own hands was just as good as any device.

The basic principle behind body enhancement is the adaptability of the human body in response to external stimuli. Everybody knows that the extra physical effort put into working out at the gym will trigger an increase in the size of the muscles that have to sustain the effort. Thus, repeated exercises focused on the penis, like the ones offered by Penis Health, are designed to force the body to start multiplying the cells that make up the penis tissues and to increase both the length and girth of the penis in order to cope with the new situation.

The best known manual exercise to make the penis bigger is the Jelq also known as jelqing or jelquing. Jelqing is a method intended to enlarge the penis by increasing the blood pressure in the penis, with the goal of permanently increasing the maximum erect size of the penis. It is done by using milking movements in order to increase the blood flow into the corpora cavernosa, the sponge-like tissues of the penis. The increased blood flow will, in time, force the tissues to expand and increase both the flaccid and erect sizes of the penis. Dr. Brian Richards has conducted a study of penis enlargement exercises in the 1970s and found that jelq helped nearly 90 percent of patients increase their penis size. The gains ranged in size, of course, but it was proven that men could add an inch or even more to their penises.
