[p.s. For those who don't know, the retarded idea behind power factor training is roughly this: Powerlifters are huge and strong. Powerlifters handle huge weight. You want to be big and strong, but can't handle huge weight. But you can lift huge weight if you use a very, very limited range of motion and poor form. Therefore, you can pretend to be big and strong by lifting huge weights with poor form through a limited range of motion. In my gym, this also is called the dumbass-workout. Power factor training adds a number weightxrepsxtime, a so-called "power factor", to the basic retarded concept above, for the purpose of making gimmicky stupid graphs and calling it scientific.]
bodhi, Mike rules. Power factor training is very, very different. Mike emphasizes (logically) complete range of motion, absolutely voluntary contraction to failure, and chooses exercises that put peak resistance at peak contraction. Benching through a few inches of motion is completely illogical. Even if you have heavy, heavy, weight, only 30% of the motor units will need to be recruited to move a bar 2 inches to lockout. So even if the weight provided an extra growth stimulus, it would only do so for a fraction of the muscle fibers. Growth will be minimal. If a myofiber is not in a contracted muscle fiber, it cannot be overload, and will not grow. I bought it too (power factor), but don't try to justify the loss by trying it. I did, you'll be sorry at the rampant catabolysis. You've been had, cut your losses, and go read Mike's book again to purge your soul. My 2 c.
