When Ray was in Sydney he gave seminars and also conducted two training camps at two of my gyms. Had two gyms then. He trained a couple of bodybuilders and one made good gains doing what Ray said.
Essentially you train body parts twice a week....once directly and once indirectly. He would alternate push and pull movements and combine chest with biceps and back with triceps done on different days. On back days the biceps are getting an indirect workout. On chest days the triceps are getting an indirect workout. Legs were on the day between. Sometimes he did shoulders and calves on the Saturday. He surely didn't do what I would say was volume training. His protocols were a challenge to finish and most people found that method too difficult and taxing. Ray and I agreed that to stimulate hypertrophy you had to exhaust the muscle and the symptoms were the same no matter how you achieved it. Ray's method got there quicker than mine. What I found was that almost all the champs needed many, many near maximal sets to get huge muscles. Ray boasted that he could exhaust a muscle in one rep. No one took him up on his challenge. I suspect that 'rep' would be sustained, etc.
Ray was quite knowledgeable about how to do exercises. Hand positions and that sort of thing made a difference so he watched for those things when helping others. I recall his changing my hand position on an exercise at Golds Gym in Venice in 1991. I was doing chest presses on a Hammer machine. Oh, about machines. For some strange reason few people used Nautilus at Golds Venice. They were in the second room so easy to access even in busy times. I guess there was a rebound from what Arthur Jones wrote so most of the muscleheads used free weights or equipment in the main gym area.
Ray stayed at my place for about a year back in 87-88. Kathy and their daughter, Dagny, stayed longer as Ray moved out. I had introduced him to Pam who he eventually married. They all returned to LA in 88.
One day when I was training triceps I finished up using a heavy stack for lying triceps extensions. Ray saw what I was doing and without any warm up proceeded to duplicate my set. After he finished he rubbed his elbows. Silly of him to not warm his elbows up. I guess he figured he was much stronger than me so could handle the weight with ease. Not so. I had been training for a while on that exercise so was able to handle more weight than anyone else in the gym in that movement. Ray was a big guy. Muscle for muscle one of the biggest guys I have seen. Somehow he doesn't look that big in photos.
One day at Golds I introduced Ray to Paul Dillet. Paul was weighing 290 that day and even though Ray was over 260 he looked small beside Paul. Afterwards he had to mention how ugly Paul's veins were. He was amazed that I had met more people than he had in the gym and he lived there. Well, Ray didn't go out of his way to talk to others. He just wanted to be left alone.
