[color=guy tension is what you are aiming for. Not mere accumulation of tension. Arthur wrote about this but maybe used different words. It makes no sense that muscles should keep growing because we merely put tension on them. What is required is a special kind of tension and that is the kind that we find when we are doing the final hard rep or two. So in any given set we would be lucky to have 5 seconds of this trigger tension. You keep doing set after set adding another 5 seconds to the total until you have 30 to 120 seconds of that tension. Your symptoms will be the same no matter what protocol or method you use. You will be exhausted, shaking, pumped and feeling great.
The reason there are so many different theories and methods is because you can arrive at the hypertrophy stimulus in many different ways. Arthur was looking for the most effective and efficient method. HIT might not be the safest.
If we look at what big guys do in gyms, disregrading the drugs for a moment, they all do very similar things. Volume training with reasonably heavy weights.
When you know that this is what you need to do to get big muscles you also know that when you see a guy like Goodrum and he doesn't have the size, well, he just isn't training heavy or hard enough. Why muscleheads would use Pilates and balls is a mystery but that is why collectively we are knuckleheads to the rest of society.[/color]
