Reports are coming out saying that the latest stretching research is telling people that stretching is useless.
In the sit down culture it's imperative that you stretch in order to prevent tight muscles from taking your skeleton out of alignment.
If your stretches are not making your muscles looser, chances are you're not doing them for long enough - or often enough.
The western world is experiencing a musculo-skeletal pain catastrophe/calamity/epidemic, caused mainly by tight muscles taking bones out of alignment. Weak muscles exacerbates the problem.
I don't know where this research comes from - probably Pfizzer, Smerk, Roach or the American College of Surgeons!
If every one did half and hour's yoga every day, doctors, physiotherapists, chiropractors and chemists would be sitting around twiddling their thumbs and playing golf most afternoons.
In the meantime stay tuned, highly tuned and keep loosening off tight muscles and strengthening weak muscles.
