Core Strength is the key to efficient pain free function. Our core muscles form a cylinder of muscle around your lower back and your abdomen. They comprise of your diaphragm, on top of the cylinder, your pelvic floor which forms the underneath of the cylinder and a muscle that acts like an internal corset forming around the outside of the cylinder, this corset muscle is called transversus abdominis. These group of muscles normally work by maintaining a low level contraction with any movement you make, to give support to your lower back and pelvis.
The technique to improve the normal function of these muscles is to do some core stability and pelvic floor exercises. Although it is important to train the pelvic floor muscles and core muscles individually, they also work together as well. Exercises like planks and lower abdominal loading can be very for the core, but must be done correctly. Physiotherapists can advise you on how to do this and other exercises to engage these muscles correctly. If you want to know more about how to train your core muscles then it is best to gain professional advice. Another good way to gain knowledge of how the core works and how to exercise safely is by finding a good Pilates class, preferably run by a Physiotherapist or specifically trained clinician.
