I agree with most of what you said, except for the part about doing the bare minimum not being motivating. I'm also a pretty experienced lifter (Been lifting for 9 years, can DL 3x my bodyweight, Squat 2.5x bodyweight, BP 1.6x) but I'm always looking for the bare minimum to improve. If that happened to be a 7 minute workout, that's what I would do. I think it's incredibly motivating to use your time really effectively. I spend probably about 1/4 to 1/2 the time in the gym as anyone else there with comparable fitness levels because I've done a lot of research on training methods and have tried tons of different programs and permutations to find the ones that are most effective for me.

I think you're right that the biggest problem with this is that there are "no discernible goals" associated with this "scientific" workout. For noticeable strength and physique improvements, the lowest I've found to be effective are 40 minute workouts 3 times per cycle with a cycle length of 7-10 days depending on the types of workouts done.
