Ok as you all know, (if you read previous posts), I am just recovering from back surgery. Now in my GXT (graded exercise tests) class my professor, who is very well known in the field of exercise physiology, actually he is one of the best, Dr. Manning is his name, explained to me that since I had back surgery, for the next few YEARS I should only do one set per muscle group to failure. He explained that this will increase muscle mass because I am doing it to failure. I am not a pro athlete, I am not a body builder, im just a guy from north jersey where its almost a requirement to be big lol, not to mention the fact that I am obsessed with having a good body. Some of the vets or people knowledgeable in the field please give me some advice as to whether or not 1 set to max will increase my muscle mass along with my AAS. I do not want to be doing my AAS while only doing 1 set and have it be worthless. Thanks guys.
