Positioning
Place your hands behind your lower back, palms facing outward or upward, with fingers interlocked or close together.
Movement
Engagement: Actively engage your core and gently squeeze your glutes to stabilize your lower body. Keep your legs anchored to the floor throughout the movement.
Extension: Lift your chest off the floor by contracting your back muscles (erector spinae).
The Sweep: While maintaining the elevated torso position, sweep your arms out to the sides in a wide arc until they are extended near your ears, palms facing down.
