This may or may not be helpful for you. I'm into a routine that produces pretty good fatigue from lighter weight. I confess I haven't been at it more than a month, yet it goes like this.
(I started with 2.5 Lbs, working at 5 Lbs currently)
Warm up with shower.
Use ESL40 Hanging Cup (Silicone cup with Eye on the end, suitable for less than 10Lbs) with a string tied to weight on one end and a metal clip on the other. The weight should be 6-12" off the floor, don't hook it close to the cup.
I then take my hand and get the weight moving forward and backward a little bit while in a slightly wider than shoulder width stance. Then I begin relaxing my groin muscles when it is swinging backwards, and tightening and a slight kegel when it swings forward. A little hip motion can help too. I call it the Pendulum. After 5 Minutes, I take off the cup, and let blood circulate for about a minute. (the cup goes on and off in seconds).
Next I reattach the weight and use my hand to get the weight swinging in a clockwise direction. I can then use my hips to swing in this way for 2.5 minutes. I then stop and go counter clockwise for 2.5 mins. This is the Helicopter.
I alternate Pendulums and Helicopters. 15-25 Minutes. Then I resume my shower for a cool down. I either wake up early or sometimes to it during a PM shower. You need a bathroom big enough to accommodate though.
The rest of my program is some light jelqing to improve circulation, and Uli and Horse Squeezes for girth. I also use an ESL40 ADS, which attaches to the leg stealthily. I try for 2-3 hours a day. It's not so much that I use it to strain the penis, but to keep it used to being in an extended state, especially when healing. My theory is that you work your penis out for a good 20 min per session, or even 2 sessions per day, the rest or bulk of the time, you are pretty flaccid and contracted. Do you want to heal in a contracted state, or encourage the cells to elongate. Just a theory, but I think it going to work. I've spent a month refining this program and I'm gonna see how it works out. I think you can cause more micro fiber tears by using low weight and rapidly changing the angles of the pull, than to just pile on tons of weight and pull in just a few directions. We shall see. I don't plan on exceeding 10 Lbs though.
