Which 1970s bodybuilder isn't? Besides, he perfected his programme on his clients, not himself. Anyway, it works perfectly well for me, I couldn't be more satisfied with my progress and thus have no reason to change my plan. I'm glad SS works for you.

For me it's High-Intensity Training the Mike Mentzer Way. Frankly I don't care about strength, and am focusing instead on bodybuilding.
I used to spend a lot of hours in the gym not really knowing what I'm doing (no plan, no goals). After this book I now have a good plan and clear, predictable goals.
Conversely, if you're done with losing fat and wish to add some muscle I would recommend the High Intensity Training technique, described in e.g. the book High-Intensity Training the Mike Mentzer Way. The basic idea is to train once or twice a week for around 30 minutes, send as big a signal as possible to your body that your muscles are inadequate, and then recover until the next session.
