Exercises such as planks, bridges, and back extensions aid in improving posture and spinal health. These exercises target core and back muscles, enhancing their strength and endurance. A strong core supports the spine, promoting alignment and stability in various movements. Additionally, incorporating flexibility and mobility work can address muscle tightness and imbalances that contribute to poor posture. Maintaining a focus on proper form and technique during these exercises is essential for maximizing benefits and ensuring overall functional health.
