Say the phrase “core muscles” and most people’s minds shoot to an image of a six-pack. But these six-pack muscles – the rectus abdominis – make up just a small portion of the core musculature, and they should not be the sole focus of your exercise efforts.
Instead, it can be beneficial to work a wider range of mid-body muscles such as the posture-supporting transverse abdominis and spine-stabilising multifidus. These muscles have become known as the “deep core” on account of their geography – they are further from the skin’s surface.
