What are the benefits and proper technique for performing the prone cobra exercise?

The prone cobra exercise can help strengthen the muscles in your back and improve posture. To perform it properly, lie face down, lift your chest off the ground while keeping your hips down, and squeeze your shoulder blades together. Hold for a few seconds and then lower back down. Repeat for several reps. Make sure to keep your neck in a neutral position and avoid arching your back too much.
