I realize that the answer may come with qualifications, such as your training age, periods when you used steroids, were eating to gain etc, but for you, what kind of training do you believe was responsible for most of the muscle you have gained? (Also realizing that you recently posted an article about how your body weight has really been quite constant for a decade plus.
The main reason why I prefer to stick with strength based goals is that you win either way. As long as you get stronger, you either are going to gain muscle in the process, or you are going to get a damn high strength to weight ratio, whatever your body is built for. Strength never really fails. Even though I have gained muscle by using high frequency low set intensity techniques, like rest pause sets to failure, pre-exhaust and overload negatives, I have never really progressed if I was not trying to get stronger on at least 1-2 lifts. Also, when I did gain muscle from intensification, it was much easier to do it on a specialization program where I was trying to bring up 1 large or 2 smaller muscle groups at a time for 3-6 weeks.
Anyway, what do you feel about rotating specialization routines for hypertrophy for naturals with a decade+ of training?
