OK. I'm trying to give specific information how I do JAI's.
I came up with this idea, because I didn't gain anything during my first three months in the wonderful world of PE. I had used these stretches in normal muscle stretching before, so I thought why not try these in PE as well.
Basic principle is that you hold the stretch for only two seconds and then release it for two seconds and repeat. Why so? Because the inherent stretch reflex (aka. kick-back reflex) starts after about two seconds stretch (in PC-muscle).
So basically I'm stretching ligs and PC-muscle too in a effective way (that's what I think). I always do a 3 X 15 rep sets after my jelqing session to support the growth maximum way. This has probably helped me getting most of my gains.
- Start breathing in and stretch your penis (I also suck in my belly at this point).
- Hold the stretch for two seconds while inhaling.
- Release the stretch but keep the grip while exhaling for two seconds (Relax stomach).
- Go to step 1.
- Repeat 10 to 15 times and keep about one minute rest.
- Repeat steps 1 to 5 * 1 to 4 times.
Breathing helps me feel the rhythm (2-second/2-second). I watched timer in the beginning to learn this. Now it's pretty much just a routine for me.
About the pulling force.. You shouldn't stretch your penis as hard as you can, because that will also lead to kick-back reflex. Just give a nice and firm tug.
Grip: Basic OK-grip behind the head (palm up). Middle finger also supporting the shaft in order to not make too much pressure on the head. Basically you can do any kind of stretches in this way.. I prefer doing circles with this standard grip.
Or try this grip on Tom's site. Link
