oh – and while it's interesting to see the principles involved when the "rich and famous" get ripped, it's usually unrealistic for most people due to:
a) amount of time available to workout as needed and prepare the food as needed
b) the cost of a high-end, high-quality trainer to advise you and keep you on track
c) the costs of eating the healthiest food in ways that tastes good
I've posted on Taylor Lautner's workout, which I think is instructive, but I'm not suggesting that the average person should or could do exactly what he did.
