Case in point: I trained a 77 year-old woman last year. She could bend at the waist and palm the floor. Flexibility manifestly was NOT her problem. She was frail and weak. Yet, as I would coach her through a strength routine, it seemed like every time I turned my back ... she'd be down on the floor stretching!
It's just what women do! They also seem to be drawn to small, poodle-like dogs. I don't understand that either.
