BULLSHIT 101

Wrongly, "Rome wasn't built in a day" has almost been relegated to the ash bin of duck-billed platitudes, due to the McDonald's culture and its gimme-it-it's-mine worldview.  Overall, there are a lot of hucksters out there telling people new to weightlifting to buy their company's magic Get Big Pill. Listen to the old-timers, who were doing nothing more than training hard and heavy and blowin' it out on steak and potatoes and fresh fruits and veggies and gallons upon gallons of milk.
It's as simple as this:

1. Develop a game plan (i.e., choose a program that will exercise ALL major muscle groups in as little time as possible - about 1 hour per training session)
2. Work out hard and heavy 2-3 times a week
3. Rest one day in between workouts (if you can workout the day after a workout, you are doing it wrong!)
4. Choose a diet based on your caloric needs (consult a doctor)
5. Focus on the process! The results will be inevitable. 

As one of my friends said, "Remember: Amateurs practice until they get it right. Professionals practice until they cannot get it wrong!"
