This is the mental equivalent of Saitama's workout from One Punch Man: 100 sit-ups, 100 pushups, 100 squats, and a 10-km run. (Repeat daily until your hair falls out.)
I dunno', this one's quite a bit worse. 100 situps, pushups, and squats aren't exactly easy like doing the alphabet. At least if someone did Saitama's exercise, they would be in decent shape, just not a well balanced in shape.
