Shunsatsuren, packing is using either a very narrow cylinder that does not allow for much lateral expansion, or filling in the cylinder you have around the outside to make the diameter much more narrow. If you search for packing you will find good instructions on this forum. If the diameter is made narrow enough you won’t need significantly higher pressures to get a lot of elongation - even at a -5 vacuum you should be able to get significant elongation with the correct cylinder diameter.
And, no offense, but your qualms about hanging do seem slightly paranoid. ;) I can assure you that nothing is gonna snap off, promise. Well assuming you are even halfway careful and don’t hang like a complete imbecile - it sounds like safety is a big priority for you, so I don’t see that being a problem.
Also, in terms of sustained, long-term length gains, I think hanging is your best option. It sounds to me like you were struggling with your hanger adjustments and attachment. Learning to get these things right can be a tedious process of trial and error, but there are tons of threads that cover wrapping, adjustments, and attachment. If you play with things for a while until you perfect your technique, compression hangers can be very comfortable. Also, it is best to only use rope if you are hanging SO or OTS. Otherwise, use a piece of wire hanger to create a small hook. Weight plates are fine, I use them, but you should also make some smaller weights: a couple of 1lb. and a 1/2lb. weights, I used fishing weights, duct tape, and a bit of wire hanger.
I should also say, you don’t need to hang. You can achieve length gains just fine through manual means. I just enjoy the very accurate application of stress that hanging allows, and it’s theoretically limitless stresses. But some manual stretching and semi-erect jelqs (50-70%) should do just fine to produce length gains as well.
Will packing produce fluid buildup? My cylinder is 1 3/4 x 9” LX. How much should I downsize from this? What have you experienced from this exercise?
No offense taken. I’ve figured out how to properly wrap up with the thermaband and cut sock. Which hanger would you recommend? Have you received any gains from hanging? How much do you hang? Maybe if I found some weights that attached directly to the hook, it wouldn’t be so unpleasant. I’ve searched the local Target & Wal-mart but didn’t find any.
Where did you get the fishing weights you used?
So far, I’ve removed clamping from my routine. If I were to split the routine into morning and evening, would you who recommend against clamping while I’m working length suggest also not to clamp at night?
One more thing I’ve pondered during my sessions: how beneficial would it be to consume food after a PE session? Like people suggest eating X amount of protein after weight training, would protein help regenerate and repair cells for PE? Any insight/ideas/experience with this?
