Stand up straight with your feet together.
Tie a resistance band around your legs, just above your knees.
Engage your deep abdominal muscles throughout this exercise.
Keeping your spine in neutral and your knees above your ankles, hinge at your hips to send your buttocks backwards whilst maintaining your balance.
Push your knees apart to put tension in the band to form a diamond shape with your legs.
Maintain this position as you take a few small steps to one side then the other.
Repeat.
