One thing I noticed throughout my career, was that the more complicated the last 48 hour prep became...the more of a hit and miss it became.
The K.I.S.S. methoed, should be a requirement for all bodybuilders.
Early in my amateur career...with limited knowledge, I attained great conditioning without making any significant changes...the more I progressed, the "smarter" I became, the more off I would come in...
Bottom line is...any great changes after you've been on the same schedule for 12-14 weeks, will backfire more times than not...
