A guide to the sporty modern fighter! The physical builds lifetime to face the constraints of the field. The author considers this evolution through the "physical versatility to last." This concept is very interesting indeed for us careers are long and grueling physically and mentally and you have to talk through the pros everyday tips. The photos are beautiful and the idea of taking action figures to show the exercises is great. This book has become my favorite book, I consult regularly and counseling to all my fellow officers. It lacks a glossary because the terms are sometimes a bit technical.
