Begin by sitting on the floor on a comfortable surface in your neutral position with both legs straight and together with your toes pointing towards you.
Now take a deep breath in and as you breathe out, lean your upper body forwards reaching as far down your legs as possible lowering your chest towards your knees.
Once you feel a comfortable stretch, hold the position and breathe normally.
You should feel the stretch in the back of your legs and your mid and lower back.
To come out of the stretch, breath in and slowly raise your body back to your starting position.
