This squat tempers rib thrust, stretches back muscles, encourages use of posterior diaphragm.
This is a great move to do after a workout, especially heavy lifting, metabolic conditioning and running. It is also great after standing on your feet all day.
1) Tuck your tail and drop your ribs to create a rounded shape of your back
2) Keep the rounded shape as you squat down
3) Keep your weight centered over your feet = do not shift entirely into your heels
4) Hold the bottom position for 5 breaths
5) Stand up with an exhale
6) Keep your back rounded as you stand
