ISO-Tension Training Principle
Perhaps my most revered principle is ISO-Tension. It's also my most misunderstood principle (right up there with forced repetitions). ISO-Tension has to do with muscle control. You can also utilize this principle by flexing a muscle when you are not exercising - just flexing it, holding the peak tension for 3-6 seconds, repeating this procedure about three times. Champions use this method by tensing all their muscles three times weekly, because this constant isometric flexing enables you to neurologically control your muscles better and allows you to bring out muscle separation and peak when you pose in competition.
