Happy Stretching

i love doing this pose. i try to do it every night before i sleep. its basically my lazy version of a stomach/waist workout. the thing is i used find this pose extremely painful and unable to bend. but with everyday practice, i can now achieve this pose and use only my stomach muscles to bring my body gradually upright again (you have to keep your feet remained where it is without any bending). you will wake up some muscles that you never thought existed.
