I started gaining again after a long plateau when I changed my routine to have two workouts a day. DLD is doing the same with his Jump Start program.
I was very happy when I saw the gains after about a month of doing am and pm workouts and thought I was on to the secret of how to keep gaining, only to find that the next month I didn’t gain at all. I feel that after of month of doing it, it either became over exercising or that my penis has got used to it and so less affected by it.
My conclusion was that two workouts a day is good for a while, then you have to change again. Or in other words - I think that the key word for me is “change”. As you know, I wrote about this in the Doing PE on an Irregular Basis thread.
Now I vary: sometimes 2 workouts a day, sometimes 1, sometimes 3 days in a row, sometimes 2, sometimes 1 day off, sometimes 3. Random pattern.
Haven’t measured yet, but it feels good. I feel I’m on the right track.
