When people talk about core strength, most think about the abdominal muscles located in your stomach region. In fact, your core muscles include numerous muscles throughout your body including your trunk, chest, back, and glutes.
I can confirm that strengthening my core has helped with my back & neck issues since retiring 7 years ago. When working (computer worker) even although I had special chair, equipment and did pilates once per week.
I now do Pilates 5 days a week and try to do a walk every day and rarely have any issues with lower back (degenerative lower spine) and neck (discectomy C5C6). Two sessions we vary using pilates ring, ball, band and small weights more intense the other 3 are more traditional and I enjoy every class. My balance is fantastic managing to balance on 1 leg the other leg straight out behind whilst pulsing ball/ring and or leg. going form sitting up on floor to lying back then back up again several times with ease using my core muscles and breathing, sometimes using ball or ring in front, Russian twists again using breathing and core muscles not neck.
There is one particular lady online I go to for home probably shouldn’t say which but she is from Australia and now in Malaysia I think she takes it slow explaining everything. definitely give it a go.
