The exercise:
1) Find a place to sit down. This exercise should be done in the sitting position so that the blood from the trunk flows into the penis. Make sure that you are not in a cramped space, and that you have some back support. Being comfortable is important in this exercise.
2) Using one hand, grip the penis near the base of the shaft, in the typical "grip hand" fashion. You should feel some pressure as you start to reduce the blood flow in and out of the penis. Apply enough pressure so that it does not hurt, but you feel the flow of blood into your penis.
Variation: if you wish, using something like a larger rubber band has been suggested by some users as an easier way. Be VERY CAREFUL if you attempt this variation, since you can harm yourself if the rubber band is too tight. You want to reduce the flow out of the penis, not cut of circulation entirely.
3) This exercise requires an erection, and at this time you should begin stroking yourself to one. Using lubricant for this exercise is ideal, and should make achieving an erection easier. If you CANNOT get a grip on your penis prior to the erection, due to either small size or large hands, wait until you have an erection to do Step Two.
4) Since the penis is now slippery, make a ring with your thumb and forefinger around the shaft. Taking your ring-hand, apply light pressure to the penis and stroke towards the head. Upon reaching the corona, or ridge between the shaft and head (uncircumcised users can feel the ridge, even if they cannot see it), run your hand back to the base. If you are using a grip hand you will feel the blood press against your grip, since you are not only forcing blood towards the head, but back towards the base.
5) Once you have mastered this grip and sliding motion, repeat at least ten times. Go slowly, you are trying to move the blood around, and not masturbating. Each stroke should take 1-2 seconds in each direction. You are now ready to move on to another variation.
6) Return to the starting position. You can leave your slide hand and your grip hand in place on the shaft. If you are losing your erection at this point it is okay to pause and masturbate a little, until you are fully erect again. Now, repeat the same motions with your slide-hand, except apply a little more pressure. You do NOT want to cause soreness, and if you feel sore stop immediately. Repeat this motion 15 times, with the harder grip. It should be almost exactly the same as the first set of repetitions, except that you will be squeezing harder with your thumb and ring finger. If at any point in the exercises you start to feel friction on the skin (circumcised or un-circumcised) apply more lubricant. Lubricant is essential in this exercise.
NOTE: one "repetition" is a stroke both up and back. Once you have reached the starting point, you have completed one repetition.
7) If you feel the need to repeat do so. A suggestion for newer users is to repeat the first and second sets of repetitions twice, and then stop. More seasoned users will want to start at 3-4 sets, and then go from there. As you do this exercise more and more, increase by one set of repetitions per week (if you are doing it every day) or one set for every 7 days that you do the exercise. This should not continue indefinitely, eventually you will reach a point where it becomes a lengthy process. Hence you should put a final stopping point, where you will stay. We suggest a total exercise time limit. However, doing the exercise for long periods of time is not suggested. Note: this exercise should not be done for more than 10 minutes at a time.
NOTE: after this exercise your penis may feel very warm, because it has been giving a very vigorous workout. By expanding the tissue vertically, this exercise seeks to optimize your length gains.
