Overall this book gives you a good intro into fitness for boxing, but my main criticisms are;
1/ There isn't enough detail about actual exercise form. If you aren't already familiar with the exercise, you'll have to look it up somewhere else.
2/ There is only 1 actual workout (beginners are told to half each exercise). Although the book goes into swiss ball, medecine ball, weights etc, none of these are included in the workout.
The overall layout is 'you could do this, or this, or this, or this', but I wanted a guide to get fighting fit - not a 'work out yourself how to get fighting fit'.
However, if you are used to exercise and building your own routines, there's plenty of ideas that are probably new to you. And even though there's only one routine - it's tough !
