I am a big fan of short workouts that don’t involve equipment & visiting gym. This Really, Really Short Workouts by Tata Parker-pope, Founding editor of Well, New York Times provides useful tips, resources & graphic illustration to follow.
Yet there is other very good book The One Minute Workout by Martin Giballa discusses importance of high intensity interval training (HIIT) for people with less time and stay fit & in shape. A must read & practice book!
