Most back pain I see in men over 40 isn't a broken back. It's a back doing jobs that other muscles quit doing. These four wake the crew back up. No equipment, floor only, ten minutes. 1. BIRD DOG On all fours. Slide one arm forward and the opposite leg back until both are straight. Keep your hips level — like you're balancing a coffee cup on your lower back. Pause, come back slow. 2 sets of 6 per side. Why: teaches your spine to stay stable while your arms and legs move. That's every step you take. 2. DEAD BUG On your back, arms up, knees bent at 90. Press your lower back into the floor — no gap. Lower one arm and the opposite leg, slow, exhaling as you go. Only go as far as you can without your back peeling off the floor. 2 sets of 6 per side. Why: your core's real job is protecting your back. This is the lesson. 3. GLUTE BRIDGE On your back, feet flat, knees bent. Squeeze your glutes first, then lift your hips until you're a straight line from knees to shoulders. Pause at the top, lower slow. 2 sets of 10. Why: your glutes are built to do the heavy lifting. When they nap, your lower back covers their shifts — and sends you the bill. 4. SUPERMAN Face down. Lift your chest, arms, and thighs off the floor, squeezing your shoulder blades and glutes together. Eyes at the floor, neck neutral. Hold 3 seconds, lower slow. 2 sets of 8. Why: the whole back side of you working as one team. Posture lives here. Run the circuit 2–3 times a week. Pain rule: muscle burn is fine, sharp pain is a stop sign. Slow beats fast. Boring beats broken. Basics, made simple. Feel better, look better, be better for everyone around you. Which one humbles you the most? Tell me below. 👇
