The core is made up of a group of connective tissues and muscles which live mainly in our torso, but influence the entire body. In essence, any muscle that attaches to the spine or pelvis can be considered part of your core. Some of those tissues act as scaffolding providing structure and stability from the hips up to the neck and shoulders, whilst others deliver power, absorb force and help us to move.
Those stabilising muscles include the pelvic floor, diaphragm, transversus abdominis (TVA), internal obliques and multifidus. The job of this type of deep lying musculature is often more subconscious and endurance based – things like maintaining posture or pelvic alignment and supporting the loads taken from movement in the arms and legs, for example.
Other core muscles are those closer to the surface which act as the big movers. They are linked to more explosive movements and include the gluteus maximus, external obliques and the much-coveted rectus abdominus…the abs.(more…)
