Why working the Core is great for posture, functionality and achieving a toned stomach! I associate the core with many different muscles in the body, however a key 'core' muscle that is possibly overlooked whilst exercising and performing daily movements in everyday life is the TVA. This is the Transverse Abdominus. This muscle can be found as the first layer of muscle underneath the Rectus Abdominus (six pack muscles).
Did you know you can activate this muscle by drawing your belly button in,( but try not to hold your breath) . Your TVA will naturally contract during lifting and acts as your body's natural weight lifting belt. The TVA whilst engaged can help support your spine and seriously reduce the impact it has on your lower vertebrae.
Exercises that help with engaging your TVA are Swissball exercises and Compound movements. While you are sitting at your desk today, try activating it by drawing your belly button in.
