I find comments like these interesting, and to some extent anachronistic. It reminds me of "conventional wisdom" thirty years ago about weightlifting in this country. Somehow it was supposed to slow you down, lower your flexibility, cause arthritis in your joints, etc., etc. As it turns out - when properly done - it does just the opposite of what all the naysayers say. Many of these same coaches also preached against having sex, because it was supposed to make your legs weak. I even had a Nei Gung teacher tell me I shouldn't have sex because it would prevent my chi development. Hmm...
A few years back I read Nolan Ryan's autobiography. In it, he talked about all the pitching coaches who said he would ruin his arm if he did weight training. Good thing he didn't listen to them. His training discipline allowed him to throw a no hitter at age 42, where his
average pitch speed for that day was 89 mph. Weight training significantly contributed to the longevity of his career.
The concept of weightlifting has gone way beyond just getting strong these days for those who are serious about it. When I say serious, I mean getting beyond using the foo foo machines in a health club (which train major muscle groups at the expense of stabilizers and don't train essential synergy or whole body coordination). It also means getting beyond bench press and curls, which is the "pleasing appearance" only aspect that Gushi refers to.
There's nothing wrong with having a little show with the go. But good weightlifting goes way beyond appearance and even strength. It's all about
balanced strength, coordination, power, tendon development, bone density development, and even cadiovascular training. It's one of many tools in the karateka's training toolbox.
And don't forget that "traditional" traning such as walking with the jars (kami) is also weight training. The only difference is that the jars don't have "Universal" stamped on the sides.
