That nagging upper back pain isn't from your phone, it's from weak spinal extensors. Fix it with this simple reset. Lie on your stomach and prop your upper body on your elbows, directly under your shoulders. Let your hips relax completely. Gaze forward to align your neck and decompress your spine. 😮 Send this to someone who sits at a desk all day! #backpain #posturecorrection #mckenzie #spinalhealth #neckpainrelief #thoracicmobility #deskjobproblems
