In a hip flexor abdominal machine, place your forearms in the pads and grab the handles. You should hold your body only with your forearms while your back is resting on the pad. Contract your pelvic floor and core while keeping your chest up.
Move your knees towards the torso until your thighs are parallel to the floor while you exhale. Return to the starting position in a smooth movement.TIPS: Focus on slow and controlled movement.
