I would consider Clamping to be an advanced girth exercise that should not be done by novice PE trainers. I wouldn’t recommend anyone with less than a year of training to attempt to clamp.
It requires a significant amount of tissue maturity and conditioning, otherwise you could injure yourself. There are no short cuts to gains, penis enlargement training is a methodical process that requires patience and dedication. The proper mindset is essential when you begin to train. This is a marathon and not a sprint. So be aware of snake oil salesmen and online sites that promise quick and easy gains!
Clamping is done while being erect in the 75% – 100% range. I refer to clamping as BFR = blood flow restriction. What you are essentially doing is forcing tissue expansion within the penile anatomy. This is primarily a girth building exercise, and will promote significant vascular development. BFR is a form of exercise in which training clamps are fastened around the penis shaft, slowing blood flow, and thus accumulating metabolites which stimulate growth, maintaining arterial inflow to organ while preventing venous return.
If you believe you have the proper amount of tissue maturity and are ready to try clamping, then I suggest the following…
First and foremost have comfortable padding / wrap under the clamp area. I highly recommend our silicon rubber Girth Bands. They are soft and pliable and provide a mild amount of compression by themselves, it will also prevent the clamp from pinching skin. Install a Girth Band at the base of your erect penis. Apply the clamp and cinch / ratchet down until you feel your penis swell. Only you can determine the appropriate amount of clamp pressure. I suggest starting with the minimum and gradually working up as you become more experienced and determine how you respond. The clamp session should not exceed 5 minutes in length. You can do as many as three clamp sessions all five minutes in length. Between each session take a five minute break and massage / jelq your penis to promote expansion and promote fresh blood flow, you should not allow your penis to turn blue or get cold! So if five minutes is too much or the clamp is too tight, back off on time and cinch pressure. Experiment with this a few weeks, as many as three times per week and see how you respond.
Once you’ve become accustomed to the single clamp, you can try double clamping, or even triple clamping. Obviously if you’re doing a triple clamp you are fairly large in length, more than likely in the 8″ + range. Same procedure…. except this time install a second Girth Band at mid-shaft and then the second clamp, and then a third girth band and clamp. Same five minute / three sessions. If done properly this exercise is a really girth builder! The vascular development of veins and capillaries is no less than phenomenal.
Never do clamping prior to hanging. You can however pump after a clamp session. I always recommend massage and moderate to intense Jelq stretches after a clamp / clamps session too, five to ten minutes should be sufficient to produce your max length and girth while still being in the 50-75% erect range.
