If you can’t make it to the gym often enough to justify that membership fee, this is the book for you. It provides you with all the knowledge you need to quit the gym and start working out at home. After reading this, you’ll be able to turn any small room in your house or apartment into a home gym. The book’s emphasis on exercising for exercise’s sake will help you look at the phrase “going through the motions” in a whole new light. Free on Kindle.
