It depends on what you want from your training. For a young buck training for football, the routine in the original post is standard and necessary.

On the other hand, at 36 years old, I have little interest in high intensity, short bursts. They only leave my back feeling tight and weaker actually.

I do believe in the concept of muscle confusion. I like to constantly tax my muscles, but that doesn't mean workouts that include short bursts. I like to switch up my weight lifting with different angles, different exercises, super sets, etc. I never intentionally max out anymore. I stopped maxing out at age 30 or so. I don't have time to waste workouts with max out sessions, and it's not that maxing out tends to cause me injuries because it doesn't. I don't intentionally do less than 8 reps of anything. I will unintentionally do, for example, 4 pull-ups when I'm fatigued.

My routine is not perfect, but it works for me. Generally, the important things for my progress have been the following: pushing hard without injuring myself, listening to my body and being consistent with my workout routines.
