Not many people know that in sitted forward bending, your belly is suppose to stick to your tight and not j let your body hanging in the air.  That is totally wrong and not counted just so your hands could touch your toes.  If you can’t reach the toes, bend your knee a little, bending forward so that your belly sticks to the tight.  Take a deep inhalation and try straighten the knee bit by bit.  Listen to your body.  Stop at your maximum and never force yourself down by pulling your feet.  Sad to say, sometimes I notice my neighbour doing that in the pre-text of showing off.  But she did not realized what she did is really wrong. Worst thing, I think the teacher is blind.  In another word, just plain lazy.

Namaste, everyone.
