Laying on the ground, with your back and shoulders on the floor,
spread both arms out either side of you.
Now lift your legs off the floor with knees at a 90-degree angle (as shown left).
With your shoulders staying in contact with the floor, rotate
your legs slowly to the left and then bring them back.
Now move your legs to the right and bring them back. Do this 10 times in each direction.
It’s a great exercise for both hip and shoulder flexibility and improves rotation around the spine.
