The Science Bit

All our muscles have fast and slow twitch fibres helping us to move or stabilise. To optimise our movement, it’s vital to maximise our stability strength. From the four very important muscles in our bodies, we can aid the stability of our whole body.


There are four important stabilising muscles of the body which will be identified and Corefulness® aims to train these muscles and strengthen them.


Serratus anterior muscle is the main stabiliser of the shoulder. When it works it gently flattens the shoulder blade against the rib cage.


Pelvic floor muscle, when working it engages an imaginary corset around the pelvis and lower back to stabilise this area.


The gluteal medius muscle is a stabilising muscle of the hip and pelvis. When it works our legs turn out and it also works to move the straight leg outwards.


The vastus medialis obliquus or VMO is the inner part of the quadriceps at the front of the thigh it works to help straighten the knee and also to stabilise the kneecap.
