I'm fixing my desk posture without doing a single back exercise — here’s the foot mobility trick a neurosurgeon taught me

When a neurosurgeon gives you advice on reducing back pain using your feet, you sit up and take note. And that's exactly what I did when Anthony Ghosh provided a simple foot exercise you can do to improve alignment and posture and reduce pain.Many people aren't aware that back pain doesn't necessarily originate at the back and can be caused by weakness, instability, under- or over-firing, or tightness in other muscles and joints, including the feet, glutes, hips and hamstrings.Within your body, you have anatomical sling systems, which basically mean a connection between muscle groups. There are four main sling systems, creating a network of fascia and muscles that recruit together across the body. For this reason, it's very important to view your body holistically rather than just focusing on one specific area when you experience pain or injury.I learned this the hard way, as years of issues with my left shoulder threw up issues in my neck and traps that I wasn't even aware of.You barely need any equipment to do the exercise below, just a chair and a few minutes to spare. Learn how to do it from a leading neurosurgeon, and why I've been adding it to my routine to fix desk posture.
