1
Sit upright on a bench with feet flat on the floor or extended. Position your torso perpendicular to the bench with your back supported. Keep your core engaged and shoulders relaxed.
2
Place hands behind your head with elbows bent at approximately 90 degrees. Engage your core muscles and ensure a neutral spine position before initiating movement.
3
Lower your torso backward slowly by extending through the thoracic spine in a controlled manner, allowing your chest to open. Keep your elbows positioned at shoulder height, resisting the urge to let them flare excessively. The movement is governed by thoracic extension and horizontal abduction.
4
Return to the starting upright position by contracting the pectoralis major and anterior deltoids. Drive through your chest muscles to pull your torso back to vertical alignment. Avoid using momentum and maintain control throughout the concentric phase.
