This routine should only be done after a couple months of PFM conditioning;
The "Resiflex"
This is a very simple but effective excersize that I've created for resistance Kegaling, with a combination of length gains. First, this is optional, get a 15% erection and kegal a little blood into the head of the penis. The second thing you do is grab just behind the head with an "OK" grip, palm facing up. Now you need a fairly strong grip to do this, while sitting or standing, with a strong force stretch straight up towards your bellybutton and hold. Now with controll kegal hard and you will feel your penis "tug back", that is exactly what you want to feel and should be hard to pull your penis back in to your body therefore creating resistance. Release your kegal and your strong upward stretch should instantly pull your penis to the starting position.
The reps:
100 then switch hands to get a fresh grip, 10 times. You should not rest while doing the 100, but once you finish the 100 take a few seconds in between to take a break and switch hands, and from the wise words of DLD, if you start to get tired finish them anyway.
10 sets of 100 EVERY OTHER DAY, if this for some stupid reason is not intense enough for you then stretch harder while you do your kegals.
