1. Grab a yoga block and lie down on the belly with the legs hip width apart squaring to the chest.
2. Cross one arm in front of the other under the chest, rest the forehead on the block and relax the muscle tone deeply, especially around the upper back and shoulder joints.
3. After 2-5 minutes release the arms out and rest for 5 breaths then switch to crossing the opposite arm in the front.
4. Alternatively, for a gentler stretch place one arm under the chest while resting the opposite arm forward and place one side of the face on the block.
