As adults, most of us have heard of the ‘core’ or stabilising muscles of the trunk. They are vital to assist in trunk stability, and joint control. The muscles of this ‘abdominal canister’ co‐contract to produce and control intra‐abdominal pressure and assist in stability and load transfer across the lumbo‐pelvic area. These muscles, or ‘core’’, atrophy, or weaken, due to pain and/or sustained postural dysfunction (eg slump sitting).
