A fighting 'travelogue',
This review is from: A Fighter's Heart: One Man's Journey Through the World of Fighting (Paperback)
A journey through various fighting systems (Muay Thai, BJJ, MMA, boxing, etc) around the world, from the point of view of someone training in them. We also get 'behind the scenes' access to fighters such as Antônio Rogério Nogueira, Andre Ward and their training teams.
I have to admit that my interest started to wane towards the end, for example, when he describes a visit to a meditation centre, and also the section on dog fighting. But overall, an entertaining read.
