Hey, it may have been a post I posted for the dude who wanted to get a tight look for Memorial Day Weekend. Glen was correct in his description, by depleting the muscles of glycogen you lose a lot of the water within the muscle, but when you decide to carb load your muscles will be more sensitive and take up the carbs, giving you the dry yet full looking muscles we all want. This is what Bodybuilders mean when they "spill over" or are "flat". Depletion workouts are used in the UD2 workout and I am currently using a similar program.
