The Jump Off: 60 Days to a Hip-Hop Hard Body

A fun and motivational book with great advice. Mark Jenkins' personal story is inspiring and the text is easy to read and understand. However, there is a glaring error in the section on how to calcualte your percent body fat. First, the equation for women doesn't work because of a typo - multiply your body weight by 0.732, NOT .0732 as the text says. Second, the resulting number is your lean body mass and not your percent body fat, as the example in the book states. There is no additional info on how to use lean muscle mass number to calculate your percent body fat. This is just lousy fact checking - the rest of the book is great and as long as you move the decimal point, you'll get a usable number. You can also use this easy online calculator, just plug in your measurements: http://www.am-i-fat.com/body_fat_percentage.html Good luck!

"THE JUMP OFF" is a book that is uplifting for all ages of adult life. I'm a senior and I appreciate what this book says about the efforts you refine as you gain a hard body. Mark Jenkins is brilliant to show his past and present life. He explains how important it is to focus on what your goals are, as he helps to teach you to take control over your body. I like this book for all my associates because we all want to look and feel our best. His examples and pictures and hard facts are tried and true. On page 110, Mark gives excellent advice for those to remember about survival in the great outdoors. From cover to cover he takes you "Outside the Box", back to your mind, and being "what you eat". I am excited again for me, staying in shape, and delighted for the millions to get a copy of his book now. Remember, this author has helped himself, and celebrities, and now he will share Body awareness with the world!
