Take More Time Off!
Have you guys noticed that in the beginning, you probably achieved fast growth, but in the later months, you hit a plateu? I recently read something interesting from AskMen - Become a Better Man about body building.
"The thing to remember is that your optimum training frequency is changing all the time. When you first start training, you can probably work out three times per week and fully recover between workouts. But as you get stronger, you begin to hoist some really heavy iron and it takes longer to recover from those workouts.
So the answer to your questions is "yes." After training a few weeks, the guy who sticks with three times per week is going to make zero progress while the guy taking time off to fully recover is going to make steady progress. "
I also noticed this. When I first began jelqing, I gained almost half an inch, and then, I hit a plateu for a couple weeks. Just recently, I began a 1-day on, 2-3 days off routine, and I’ve gained more than 1/4" in a 2 weeks.
So if you all of sudden begin slow growth, or stop all-together, try changing your routine so that you get more days off. The more advanced you are into PEing, the more days you’ll probably need off. Just my theory. Hope this helped.
