Failure training is a bad method to use for strength training because it traumatizes the CNS, and taxes recovery rates to the extreme. Take notice of how the Westside guys, and Russian Oly lifters train but notice that they don't use Max effort days very often, nor do they train the lifts they are trying to improve directly. This has a lot to do with keeping the CNS fresh and capable of performing the tasks required of it at every workout. Each day is used to imrpove, not to debilitate. Use different planes of motion, change up your set rep schemes, and utilize rest period between 1-2 minutes and your strenght will go up. If you train your whole body in one session do your multijoint exercises at the beginning and at the same time use completely different parameters on a three day a week program. Like Day 1 3X8, Day 3 2X15, Day 5 5X5. Use this style of training and you'll grow like a weed. I've seen it with my clients over the last few months, and regardless of where they are developmentally. It keeps the CNS fresh, no overtraining, and it also elevates GH production, T production, and lipolytic enzyme production. Just a few thoughts.
