I have used a 2 day per week Texas Method with great success. I have the Kindle version of the book so the page number you have does not work for me. I have tried 3 workouts per week and 4 day splits. Both of these lead to shoulder pain. It's an old injury from youth. My left shoulder has a lot of scar tissue and inflammation will accumulate if I don't give it enough rest between workouts to recover. 2 days a week works and the 2 day Texas Method has been a good program.
Here is what I am doing.
Monday
Bench Vol
Squat Vol
Dumbbell Row 3X10
Press Vol
Barbell Curls 2X10
Thursday
Bench Intensity 5/3/1 Rotating reps
Squat Intensity About to start 5/3/1 Rotating reps
Chins 3X(AMRAP) Alternating weighted/BW
Deadlift 3X 8/5/2 Rotating reps
Triceps 2X10
I am going to take a break for a while. I consider this TM a Heavy/Heavy program. What I am going to do for a while is the same exercises but in a Heavy/Medium format. Intensity day will be 3X5 at a slightly reduced weight from volume day. You could also do Heavy/Light if more recovery is needed. Very flexible.
