Stand in front of a high table or worktop.
Place both hands on the top of the surface with your fingers pointing fowards and lean some weight onto your arms.
Ensure you have a straight line from the top of your head to your heels.
Keeping your abdominal and buttock muscles activated, drive your hands into the top of the table, flattening your shoulder blades against your back.
Keep your neck in a neutral position looking down and slightly ahead.
Your neck should remain long so ensure you do not allow your shoulders to hunch.
Hold this position, relax and repeat.
