Woman crouches down and holds end of a yoga mat. My posture has never been great, but after months of holding my toddler all day, I started to notice that it was getting even worse. When my go-to exercises weren’t doing the trick, and my mid-back would ache by afternoon, I knew it was time to get serious about addressing my poor posture. I’m a certified personal trainer and I know of the benefits of prone spinal rotations, and thought they could be a game-changer for my back health.
