Mirroring the first two images, sit on a sturdy chair with your hips and knees at a right angle and a wide gap between your legs.
Place your hands across your chest.
To start this exercise look forward.
Lean backwards over the back of the chair to bend your back backwards.
At the same time extend your neck so you are looking up towards the ceiling as shown in the third image.
Hold the position for 3 seconds then return to the starting position.
Repeat 5 times.
