Protein is just one of those somewhat controversial topics that there just doesn’t seem to be a clear consensus on. How much, how often, what types of protein – fast, slow, whole food or supplements.
A normal contest prep for a male bodybuilder is usually in the 10-12 week range – but if you stay lean year-round (something I recommend) you can probably get away with half that. It doesn’t need to be all that complicated. Drop carbs, up the protein and add some daily treadmill or stepmill sessions of 30-60mins. Throw some fat burners in the mix. Rinse and repeat until lean.
