What does it take to build solid power and size? Gaining lean body mass is the Holy Grail and the Lost City of Gold and the Atlantis of bodybuilding. It gets talked about a lot, but few seem to unlock the secrets. In the past few decades, Dan John, author of the bestseller, Never Let Go, has found the key to this enigma-It is based on a few principles, a few days a week in the gym and a few key movements. It sounds simple because it is simple. But don't let simple fool you. This isn't easy. Set aside six weeks, prepare a gym bag to stock with food and enter the world of attaining lean body mass with Dan John as your guide.

In this electronic version, when you get to what would be page 121 in the print book, you'll be given a link to a printable PDF version of the training log pages.
