@jesseblu.fit: Most people think back extensions are just for your lower back, but they’re so much more than that. They strengthen the muscles that stabilize your spine and core, helping you maintain a stronger, more rigid torso during heavy lifts like squats and deadlifts. A stronger posterior chain means better force transfer, improved posture under load, and a lower chance of your lower back becoming the weak link. #gym #backexercise #Fitness #glutesworkout #explorepage✨
