Added water weight hinders performance? News to me.
Hence why I added depends on what you wanted to perform better in. There are many situations where added water weight can hinder performance; gymnastics, boxing (making weight), wrestling, MMA, etc.
Consider the sporting scope to much broader than bodybuilding and powerlifting.
Perhaps not entirely relevant, but still worth considering before adding creatine to the list of staples.
Also PROness said it as a general response, as if creatine aids everything; it only has a real impact in sports where maximal intensity is required i.e. sprinting, lifting etc., not in aerobic endurance events. Just clearing that up
