The basic idea of this book is to work the body in about 15 minutes.
Here's how you do it. You focus on a few key exercises and move quickly from one exercise to another, with mininal rest time between exercises. Then, you repeat the exercises in a circuit, again with minimal rest.
These workouts work on increasing strength, by building muscle and strong bones, thus burning more fat. These workouts emphasize getting a lean strong body, rather than bodybuilding, and is, therefore, not a general bodybuilding book.
In the number and variety of workouts, this book is excellent. It contains 78 workouts, all 15-minutes long. Some workouts are bodyweight or require dumbbells. Others use a pull-up bar, a barbell, a kettlebell, a medicine ball, a stability (Swiss or large) ball, an exercise band (tubing), a foam roller, a jump rope, a BOSU, a bench, a cable machine, a step, and so on.
Instruction and exercises for each of the workouts vary, but in general, one may do a circuit of 3 to 7 relatively intense exercises, with little or no rest between each exercise. Then, rest for 60 between each circuit. Finally, repeat 2 more circuits.
All exercise photos are large and in color, clearly showing their positions, with descriptions.
Here's a detailed list of the 78 workouts or exercise plans. I have listed the exercises for a few of the workouts.

I did workout #3 (bodyweight) and I was breathing heavily during the exercise and I did a modified version of workout #7 (dumbell blast 2) and it was intense and made me sweat. I loved the concept of 15 minute workouts and I liked this book.
If you liked this book, try the women's version of this 15-minutes book. This shows more bodyweight and dumbbell workouts.
If you want just bodyweight exercises, (with no equipment), get this book, "You Are Your Own Gym: The Bible of Bodyweight Exercises" by Mark Lauren and Joshua Clark. This is excellent in the range of exercises which, again, do not require equipment.
