"I eventually realized the vast level of overtraining that even HEAVY DUTY was creating in advanced trainers with extremely efficient neuromuscular pathways. In these unique, highly trained individuals, even most abbreviated, high intensity training programs may be too much. For these individuals, I've developed a highly advanced form of Heavy Duty. It involves the use of just two exercises, performed at opposite ends of the calender year. One all out set of Nautilus pull-overs, completed to failure, along with forced reps in early May, and one all out set of Nautilus Leg Press, completed to failure, with 1/4 reps to positive failure in early December."
