Dylan Mentis | NASM CPT, CNC | Stretch Specialist on Instagram: "If your low back tightens up every time you hinge, try this. Prone core rotations train your core and QLs to manage rotation and hold tension where it matters. Pair them with controlled back extensions and you build a low back that’s not just looser, but stronger and more resilient. 👇 Save this and add it to your next lower-body day. Comment “LOWBACK” if you want more core and spine-friendly progressions. #lowbackhealth #coretrain
