'cuse me do you overpronate? (A simple test)

This is a simple test to see if you pronate when you walk/ run, tip courtesy of Dr. Low of the Shape workshop, shared by daisiki on the sgrunners forum.

1. Stand on one leg.
2. Bend other leg backwards.
3. On your standing leg, slowly bend and stand up again.
4. If you cannot do the above without trembling, it is likely that you pronate.
