STARTING POSITION:
Place a chair in front of you and put your right foot on it. Place your hands on either side of your hips. Contract your pelvic floor and core while keeping your chest up.
MOVEMENT:
Slowly move your hips forward by bending your right knee until you feel the stretch in your psoas muscle. Make sure you don't arch the back. Maintain the stretch during the required time and then do it with the other side.
TIPS: You should feel the stretch of the muscles but not pain.
