STARTING POSITION:
Stand straight with your feet shoulder width apart. Move forward your right foot and raise the heel of your left foot. 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 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.
