I recommend this book to martial arts instructors who don't use flow chain drilling in their practise.
It doesn't matter if it is for mma or any other martial arts style/sport. Any style can benefit from this methodology.
I think it's paramount to integrate offensive and defensive techniques in progressive drills so that the trainees can develop a sense of when it's good to defend some sort of attacks with certain type of techniques or how to naturally follow a (counter)offense.
To train this way for martial arts I think it's a much better option than attending striking classes and grappling classes by separate.
It's a very good way to drill. Novices can benefit of this methodology because they can train their parts with medium to high intensity since practically the first day.
I have seen training partners learn new movements throughout certain class with drills like the ones described here and later apply them in sparring practise.
