FROM MATTERS OF SIZE
http://img27.imageshack.us/img27/7600/mandingoo.th.jpgIn a standing position grip your dick just beneath the gland with an OK sign with your palm facing down.
Now rotate your hand 180 degrees so your palm is facing upwards.Your whole dick except the glands should be on the knuckles which serves as a lever point or fulcrum but because of the rotation of the fist it also bundles your dick(bundling can be controled you can bundle your dick multiple times thats up to you) similar to DLD-s double bundled strech.
Now when you are in position where you have rotated your fist 180 degrees(or more) and your palm is facing up with you holding the dick just beneath the glands and your shaft is on you knuckles your down side of thr palm should be resting around your belly which wil enable you to generate incredible amount of force without spending energy.
Now for the final part.The way you generate leverage is simply by bringing your wrist upwards without moving any other part of your arm just using your wrist as a leverage(your fist is on the belly).You dont pull upwards like in an upward stretch rather its an adduction of the wrist shown in the 3 rd exercise on the next link http://www.exrx.net/Articulations/Wr...l#anchor263084
When doing the stretch you should feel extreme sterching of the inner penis from the shaft all the way to the ass if you put your hand on the part of the dick thats closest to your ass you should feel extreme hardness.
The stretch is very painfull also.If you dont feel extreme inner dick strecth you are doing something wrong.
On little thing.If youre dick is 2 big put some pading around your knuckles so it spreads better around your knuckles enabling you more tightness.
One last thing i wanna give credit to DLD whos done great thing for PE comunity with his hard work and inovative exercises that take 1000-s of hours to be created.
The pictures are working.
