We're going to talk about enlargement exercises for a bit. And the program we are focusing on is "Penis Development". If you want a hard copy book version, Click Here
The basic idea of the exercises are that you massage and lengthen your penis without using free-weights or any other scary type of actions. All you need is a hand and a penis to take part. You massage areas, you use your hand to access pressure points and more.

The real reason that this program appeals to so many people is because it doesn't involve anything "scary" persay. There are no pills to take, no devices to wear, no creams to rub, no sprays to spray and no tonics to drink. All you need to do is... well to be honest "play with your dick". :)

Inside they show you methods that have been used for many years. Pictures help you see exactly how to do it, and the massive amount of information helps you understand as well. There is a lot of steps involved and the program requires some time. So you will not be just eating some sticks and expecting to see inches on your penis within hours.

Exercises are proven to work, and the most comprehensive site we could find was Penis Development

Here is are some exerpts from their site:
"The penis has three main chambers: two larger ones on top and one smaller chamber on the bottom. The medical terms for these chambers are: (Corpora Cavernosa) and (Corpus Spongisum).

When you get an erection, blood fills these chambers. The main blood holding tissue is the Corpora Cavernosa. Your penis size is determined by the amount of expansion that occurs within this cavity. Once the maximum is reached, you are at full erection. This is where our program can benefit you. The tissue in this chamber can be safely increased in size, to improve your penis size and we show you how.

We provide you with full detailed instructions packed with pictures, animations, and movies on the specialized exercise routines that develop the Corpora Cavernosa. As the tissue in this chamber increases, both in length and diameter, your penis will become larger. This is somewhat like working out in the gym, although your penis is not a muscle. The more you exercise, the better conditioned you become. The secret is knowing how to exercise. Consider us, PenisDevelopment, to be your personal trainers in this arena.

Within 10-14 days, you will start seeing amazing results. Your penis will begin to hang lower and have a more muscular appearance. As you continue with the exercises, you will notice other benefits. Increased circulation within the penis will stimulate your nerves, making your penis more sensitive and pleasurable during sex. It is common for many men to see a 1-inch increase in penis size within 4-5 weeks or less.

We also provide invaluable information on how to increase the size and volume of your ejaculations. Make each and every orgasm feel like thunder! Your penis will gain a very muscular look, both when erect and flaccid. You will "stand out" in any crowd. "
