There are tons of factors that go into progressive resistance training. All must be dealt with properly. I feel, with myself, that my diet plays a large role in how strong that I am. I know that the intensity is going to be there, the attitude, the proper program, and rest...but diet is the one thing that always fluctuates. I must concentrate on eating a lot of food...and often.
For me...diet is the most important...even though my diet is a lot different from most others.
