Query: SAVE YOUR MONEY--BUY THE MAGAZINE "MUSCLE MEDIA"

this book is weak and poorly written. it raises more questions than it answers. the jist of the book could be summarized in 10 pages saving readers the tiresome,preachy philosophy lesson. if the book encourages and motivates readers, fine. however, as a detailed, "how to", step by step guide, it falls short. a much better book, very detailed and quantitative is The Lean Routine. I don't recall the author's name. Finally,I would suggest buying the magazine and saving your money - the same information is found in the magazine.
