This Works (Dynamic Stretching)

I have found a wonderful and cheap alternative since posting that, at post #119 of this thread,
$15 electric vacuum pump for anyone!

AND mo1258 has a wonderful post on how to set it up at post #136.

A word of caution is that this pump pulls a vacuum apx 20 in hg, so for safety set your regulator down to the safe range you are intending on using if you buy it.

Took the weekend off after over 2 weeks of daily pumping. I did get a new max length under vacuum (LUV) after taking the two days off, so this week I am going to just do one on and one off and then then weekend off and see what happens.

I heat for 5 minutes under IR lamp, then use 3-5 in hg for about 10-15 minutes to get relaxation, then 15-20 minutes dynamic pumping with gradual increase of vacuum, by slowly pulling my unit out to longer and longer increments that are marked on my cylinder. I go by feel, and keep it feeling comfortable with slight discomfort of stretch. I finish up with hitting max LUV or slightly beyond if possible and shut off the IR lamp for the last 5 minutes and let it cool down at max LUV.

EQ has been great, flaccid hang great. Today I got more discoloration than normal, because I was using a HTW (hair tie wrap) like a condom. Because I couldn’t see my skin, I pulled a little too much vacuum to fast and got a lot of discoloration. However, the dynamic pumping helped remove a lot of the hemorrhage in the skin so it ended up moderate instead of a lot.

I had set my max vacuum value at 15 in hg, but I just realized I may have changed it, I will have to go and check it out. This pump can pull up to about 22 in hg, so you really have to be very careful!!!!

Nice how this thread is going on, very interesting. :up:

I have not seen the insides of larger model aquarium air pumps but I assume they are of similar design that allow conversion to vacuum. I am interested to know if the larger models will pull significantly more than 5”Hg or they just move more air volume at about the same negative pressure. The advantages of the aquarium pumps is that they are readily available, come in an enclosure and are quiet.

This “Dynamic Stretching” or “Dynamic Pumping” or whatever you want to call this technique is an interesting approach and also has me wondering about how/why this might work. I wish I knew Italian as I think Mr. Fantastic and others on the Italian forums are also discussing this technique…

What is the effect of the minimum vacuum on edema? I suggest that 0 (zero) minimum vacuum results in less edema. In other words:
0”Hg -> 8”Hg -> 0”Hg is better than 3” Hg -> 8” Hg -> 3” Hg
perhaps there is less time for fluid to cross the cell membrane…

So, just to identify the variables:
minimum vacuum
time from minimum to maximum
maximum vacuum
time from maximum to minimum
# of cycles or total time

That has been ;my experience, that going down to 1 or 0 in hg results in less edema than going to 3 or 5.

Think of it this way, under a certain level of vacuum the capillaries begin to leak blood or plasma, going beyond that can rupture them, causing the “red dots”. If you keep going, you get larger and larger blood vessels that can blow out.

This apparently differs with people, as some can use constant vacuum at much higher levels than others and not get bleeds or edema. I particularly have sensitive or “weak” capillaries and using constant vacuum I get red dots at 3 in hg if I go past 10 minutes. So, the trick here to use higher vacuum levels or even modest vacuum levels and not get a lot of edema or rupture is to raise the vacuum levels and then rapidly drop it back to safe levels (for you) before blood or edema leaks out of the capillaries.

For me, I am able to take it up to 15 in hg and get minimal red dots or edema IF I drop it rapidly down to safe levels. I have experimented with dropping it to 3 or 5 in hg, but as mo1258 mentions, I get a LOT more edema and ruptures if I do that.

I have also found that its important to SLOWLY raise the vacuum levels. For example, if I go into the tube and slowly raise it to 15 in hg, I will have tons of red spots! What works best for me is to maybe start with 3 in hg max for a couple minutes, then drop it and raise it back to 5 in hg, drop it back, raise it to 7 in hg…etc. I take about 10 to 15 minutes to reach the max of 15 in hg, and as long as I do that, drop it rapidly down to 1-0 in hg and use heat, I can get away with very little edema and red spots.

Take for example, today I went up to the max vacuum levels too quickly and I got significant blood in my skin, about a third the size of a dime, in several areas. What is interesting is that by going to lower levels of max vacuum and dropping rapidly to about 1 in hg rapidly, it cleared out a lot of that blood over the next ten minutes.

I also find that if I pull too hard too fast on my smooth muscle (in the penis) it wants to reflexively contract back. IF I use a lower vacuum level for the first few minutes like 3-5 in hg for 10-15 minutes, it “coaxes” my smooth muscle to relax and I get a long length with far less vacuum force. THEN I am nicely warmed up and proceed to “stair step” the vacuum levels up to my max.

What is exciting for me is that I have long had the sneaking suspicion that there may be a minimum time needed pumping to really start to see results. For many guys, they find 20-30 minutes is needed to get gains to begin. I have a vague recollection that Ron Jeremy had said anything less than 60 minutes is a waste of time! Well, for me, even 3 in hg causes red “dots” that progress into “spots” and then sores if I get going with it! Now, with this understanding, I am now able to push into the 30 minutes zone with only minimal problems as long as I drop the vacuum in proportion to the max vacuum used.

For example, like Cap uses 3 in hg, and drops it for 15 seconds apx every 5 minutes. When I use 5 in hg, I drop it every 2 minutes. When I use 10-15 in hg, I must drop it instantly! But I am seeing positive changes in EQ using this method, including more nite wood, harder erections and heavier flaccid hang. Now I just want to see if I get some gains with it. Time will tell! But I can’t say this enough, if you are going to use higher vacuum levels, you can really damage yourself so study up first, then proceed with real caution!!! High vacuum levels can cause permanent damage that may be unfixable
!

I have found exactly the same thing, raising the pressure too fast or even slightly too high causes a reflex contraction.
Your body doesn’t like being stretched beyond normal limits so you have to kind of sneak up on it.
I’ve found if you feel like you’re getting contraction either dropping the pressure for 30secs or holding a kegal for a few secs can relax things off again.

Measured yesterday after using the cyclic pump device for 2 on 1 off over 4-5 weeks, (weekends off). Can confirm a minimum of 3mm increase in length in that period! Very happy :)

Good news !
What minimum and maximum pressure are you using and how long are the sessions ?

5 min, 15 max - Some stretching before and afterwards. 30 minutes max.

Thanks sparkyx for posting the link, great info there. It’s a very easy modification to the aquarium pump, took me 15 minutes to do the whole thing with just a screwdriver. I like how the aquarium pump does its thing at a consistent, steady rate whether you want it rapid or slow. Like with anything in PE I would NEVER leave any device being used to go unmonitored so I’d never leave anything on “auto-pilot” while it has my ding-dong in it. That’s what I love about the thumb regulator method. Though it’s not as exacting it does leave it wholly to “feel” and you focus completely on cycling the vacuum amount up & down and not having to do the squeeze, squeeze, squeeze thing. I suppose I should eventually add a gauge but then again I’m not working with high pressures with my zero tissue compression experiment. It’s coming along nicely, feeling a slightly plumper flaccid. Holla.

Yeah, once you go “electric” you never want to go back! Just hook up your pump that has a gauge on it, to measure its max vacuum level, so you know. You can hook it up like the thread shows to regulate the max level also.

AWESOME!

Great Can you give us some more details of your current PE routine. I gather you are doing manual stretches before and after. Are you also jelqing?

I believe I have a similar pump as yours though I got mine some time after you. I am dynamically pumping in the evenings and extending in the mornings and also do jelqs. Believe I am still gaining length but need more time to be accurate.

I have definitely gained girth and my EQ HAS improved.

Tried this method for the first time today. I must have held the stretch too long. Today was the first time I have really noticed red spots from pumping.

I started dynamically stretching about a month ago after reading this thread, first with a LeLuv hand pump and more recently with a Mr Fantastic electric pump.

It definitely seems to work for length, girth and for EQ (if you need help in that area as I do).

The posts by SparkyX, Capernicus1 and Firegoat about the effect on the tunica are thought provoking but I am not knowledgeable enough in that area to contribute in that debate.

However I have a couple of thoughts.

Firstly I see a similarity between Dynamic stretching and jelqing as moth involve cyclic stretching of penis tissue. Jelqing seems to be a well regarded means of enlargement so it reinforces the idea that cyclic (eg dynamic) stretching does work.

Secondly Rootsnatty has recently started a couple of excellent posts on stress relaxation extending and why he believes stress relaxation works better than creep. My Stress Relaxation-based Traction Device in Action and More Hanging Sets or Adding Extender.

I suspect he is right that stress relaxation might be better than creep in creating gains and I also suspect there may be some connection with dynamic stretching. However Rootsnatty suggests cyclic stretching would toughen tissues and make gains less likely and raises the concept of Hysteresis.

I have a physical science background but have no training in biological science so cannot question Rootsnatty’s conclusion. However, if dynamic stretching is working there must be an explanation of why.
