As the name suggests, our core muscle is the core of every move we make. Whether you are running, walking, pulling or pushing, your core muscles are engaged in all kinds of activities. It is one of the largest muscle groups of the body, consisting of your internal obliques, external obliques, transverse abdominis, rectus abdominis and the erector spinae. Having a strong core is important for both men and women. While there are several exercises you can do to target your core muscles, there is one particular move that targets your Transverse Abdominis (TVA) muscles, which is necessary for every woman.
