I propose a much more abbreviated and scientific method to activating the nervous system. My method involves "overshooting" the training load for 1-2 reps in order to activate more motor-units without inducing any excess fatigue. This method is similar to a technique used by the mighty strongmen of the past called "heavy supports." (For those of you who don't know, heavy supports involve holding a supramaximal load {110-160%1RM} in order to activate more motor units and strengthen tendons and ligaments.) Here are the specific guidelines I have found most beneficial:
Overshoot percentage: 10-12% of training load
Training load must be submaximal (70-90% of 1RM) in order for the overshooting to be effective (obviously if you are testing your 1RM for the bench press you will not be able to perform 1-2 reps at 10-12% over your maximum, you would use the "heavy supports" method instead).
