How to correctly perform Supta Padangusthasana:

1. Come onto a mat and lie on your back with your legs outstretched.

2. Bend and hug your right knee into your chest.

3. Place a yoga strap around the ball of the right foot. Hold the ends of the strap with each hand. If a yoga strap is not readily available then use a jump rope or another type of strap.

4. Straighten your right leg up towards the ceiling while tightly holding onto the strap.

5. Stretch your right leg upwards with the foot flexed, but keep the ball of the hip joint resting in the socket and both sides of your bum equally pressing into the floor.

6. Keep the left foot flexed and the left leg pressing towards the floor. Remember, you are still in Tadasana, Mountain Pose, even while laying down!

7. Hold this position for 5 to 10 breaths.

8. To come out, bend the right knee back into your chest, bring the left knee to join it, and then repeat and redo for your left side.
