Warning!
You can injure your spine if you do not carry out this exercise correctly.
Place the door frame bars between the door frames as shown.
Lay on your back and clamp your feet under the central bar. Angle your legs so that you
avoid a hollow back. You may place your hands sideways on the back of your head so
as to avoid excessive pressure to the head. Now pull the upper body slowly upwards
with the aid of the stomach muscles. Retain this position for a few seconds before
lowering your upper body down slowly.
