Core and erector spinae activation are key for correcting flat back posture. In this condition, the natural curves of the spine are reduced, leading to stiffness, imbalance, and poor shock absorption. Strengthening the deep core muscles supports spinal stability, while activating the erector spinae helps restore the natural lumbar curve. Together, they improve posture alignment, reduce back strain, and bring back healthy movement and spinal balance. Be Healthy!💜 - - #posture #posturecorrection
