Book excerpt: If there's one obstacle to selling wellness books to guys, it's this: none of them are written by professional wrestlers.In the nick of time, the one and only DDP-Diamond Dallas Page-steps out of the ring and onto the mat to offer Yoga for Regular Guys. Most yoga books marketed to men are earnest and straightforward. Yoga for Regular Guys brims with guy humour and an extremely irreverant attitude but still manages to pack in a legitimate, comprehensive and rigorous introduction to real yoga practice. The foreword is written by Rob Zombie of the band White Zombie.
