Is Jason Feruggia’s new book different than the e book that came with his Get Jacked book?
HI, I do not know about his previous book but the Tapout one is by far the best book for combat sports conditioning. I have just about every book and video on the subject and the reason I like Jasons book is it has about 4 routines you can follow, these routines will not leave you overtrained and you can continue to follow your martial arts training on the side. I can let you know what other material I have found useful if you want. Hope this helps.
