Black Jack, I was reading on article a while back on strength training for athletes. The author recommended using isometrics for about 30 % of your exercises. I basically do a horse stance, and a cat stance, very low for my lower body, and for upper body, I lower myself halfway in a pul up positon and hold, and do the same with dips. I'm just coming back off being sick, but I can feel the difference under the bar already. Try it for a couple weeks at the end of your workout. It takes about 5-7 minutes at the end of a session. It works better after you've already smoked your body.
I have no idea what WD is talking about.--Royal Dragon
