Lots of theory material on Art Jones ideas, written by himself in his somewhat famous white papers. Lucky enough to read them when I was a teenager. Mentzer (along with brother Ray) also has much material floating around on the internet. A few sport training labs find them helpful, as; colleges, research departments, etc..
Probably the original concept of the 1 set to complete failure was begun with the breathing squat program. Added a lot of muscle mass to a lot of men over the years. 20 reps (or more) starting the sets with 3 heavy deep breaths. When reaching the last 18 to 20 reps, will probably need 6 to 8 very hard breaths. This would be a version of the old Rest-Pause system, with the time it takes, between reps, for the extended heavy breathing.
All this is geared towards whole body compound exercises. Example would be, squats (as mentioned), Dl's, C&J,C&P, cleans/hi-pulls, etc.. BP's,overhead presses, curls, etc., for example, seem to fall short for max gains. The one exception, for me anyway, is the bent arm pullover & press for 20 reps. An exceptional method for increasing the mass of the upper body.
Only time anyone might try going to complete failure is with a one set 20 rep program. There is positive , momentary, negative and complete failure. Actually, if you work hard enough, all or most of these can be accomplished in one total set of 20, or more, reps. The CNS will be fried.The oxygen debt exhausted. Intensity of the highest order. Good Luck.
