Stand with your body in a supine position. In the supine position the body is lying on its stomach, then in a horizontal position, with its back resting on the ground or other surface, and with its front facing upwards.
Keep your legs stiff
Now from this position perform a Sit Up, bringing your arms up
In practice, the arms and torso move in unison where at the end of the movement the torso will form almost a 90 ° angle with the legs and the arms are straight behind the ears.
