About this Book

Natural Bodybuilding Systems (NBS) published these two workout programs back in 1992 as a means for exposing the muscles to the ultimate in mass and muscularity. 

Both programs utilize a six days on, one day off training frequency as the preferred method to ensure a continued gain factor without the encountering of training plateaus. Bodybuilders universally enjoyed the six days on-one day off training frequency within the two separate workout programs because the controlled and frequent day to day training sessions of each lasted only a limited 60 Minutes.
