Hi Guys,
I agree with simon15 on Ross Enamait. I have been using all three his books and he really takes high intensity to another level with the simplest of workouts. what’s really great from his training is the increase in strength for his body size at no loss of extreme explosiveness!
all three books available from his site http://www.rosstraining.com and http://www.rossboxing.com
enjoy and chat soon
