OK, so I start stretching my hamstrings every day, for ten seconds. Within one week, I can touch my toes, and by the second week, I can rest my palms on the floor.

This is not increasing my "range of motion"? It's simply increasing "joint flexibility"? Aren't we talking about the same thing here? Is there something shameful about stretching that I am not aware of, that I should feel defensive towards? I really don't get the aversion, but different strokes ... I'm just gonna keep stretching because I'd be a cripple by now if I didn't.
