Put simply, core is your internal abdominals. Our abdominals are made up of layer upon layer of muscle, and it can be tough to know when you are effectively training your core, because they are deep muscles and you cannot see them. Core training is different to training your abs (rectus abdominus). Your six-pack muscles are the superficial muscles responsible for spinal flexion (crunching forward), where as your core is responsible for strength and stability in twisting, rotating and day-to-day functional movement.

Core has become hugely popular in the fitness industry over recent years because it is largely responsible for supporting the spinal column, stabilising the pelvis, and holding us in an upright position. By keeping our core strong we can prevent back injury, learn to correct our posture, and build a stable base that will enhance our performance in sport.
