Most people think they can just go to the gym and they will grow lean muscles in all the right places. Unfortunately, it doesn't work like that. To put it simply, I tell my clients: Lean muscles are made in the kitchen, built in the gym, and grow in your sleep. This is why you've got to eat all the right nutrients in the most balanced portions, execute the most effective exercises consistently, and get enough "rested" sleep at night. It's a science. It's an art. There's no short cut. Period.
