Nice, and you're right. Light muscular damage would be repaired quickly. If you're interested in maximum growth, why not go to maximum damage and then the needed rest? Why go to the gym and work lightly only to come back the next day and do it again?
And if you'd read what I wrote you'd see I never said I'll work out just 12 minutes a week. I said I'm jacking it up by doing twice more exercises and going to failure three times each. But I think I'll reduce it because I literally feel as if I just left the gym and it's been 48 hours.
