This was one of my primers when I started to learn boxing. It's strengths are 1)speed bag routines, 2)jump rope routines, and 3)hand wrapping techniques. For those without access to a boxing or kickboxing gym will find this info very valuable. The weaknesses of this book are 1)only two or three heavy bag routines, and 2)No double end bag routines. But, all in all it is a very good book.
