When you injure your back people will often tell you that you have to strengthen your abdominals.
The statement is correct but doing sit-ups while you have back pain will increase the pain considerably. It is necessary to increase your Transverse Abdominus strength. This is a very deep muscle that directly supports the lumbar spine. People with lower back pain often have a very weak TVA and therefore have nothing stabilising their spine when playing sports or when lifting.
This set of muscles is initially difficult to exercise and you will need some instruction from your physiotherapist.
The benefit of exercising these muscles are to:
Increase the strength of spinal stabiliser muscles, therefore reducing the occurrence of pain
Improve the strength and tone of the abdomen
Improve incontinence – or post pregnancy issues
Prevent back pain
A lot of these physio exercises require supervision to see if correct muscle groups are being activated.
