Written by Sean Nalewanyj, Truth About Muscle Gain is a very comprehensive step-by-step guide on special workouts and routines that produce some of the most dramatic results that I've seen. Program includes a 249 page guide, workout plan and logbook, database of 100+ proper weightlifting exercises, mp3 audio courses and even an advanced progress tracking software. However, the component I find most effective are the online muscle building videos that are targeted at the specific major muscle groups. These videos are the ones that gave me significant results fast and maximized my workout. Sean also provides 3 months of online personal coaching and one-on-one email support. He is very knowledgeable and always willing to help.
