Extend one leg out in front of you and tuck the other foot in next to your thigh. Raise your arms overhead, straighten your back and inhale.
Then bend forwards over your outstretched leg and exhale. Stop bending when it doesn’t feel good to bend any further. This is Janu Sirsa asana, the head to knee pose.
Close your eyes and picture what you would look like if you could stretch even more. It works. Just by thinking about it, you will be able to stretch a few more centimetres and even touch your ankles.
Do the forward bend with each leg, then both legs together in the full forward bend, Paschimottana asana
