Tried it for six months, mostly body weight exercises and dumbbells, three to five times a week. Aside from a moderate improvement in fitness (which I have no interest in), it changed nothing at all. No increased energy, no happy feelings, just a waste of time.

It’s true. I injured my left ankle freshman year of high school and I’m in my 30s now and still roll it semi-badly to badly around once a year. Stupid thing is so weak.
