Your Posture Exercises May Focus on the Wrong Thing
Stretching tight chest and shoulder muscles is the most common advice for improving posture. It also barely works on its own. Research consistently shows that stretching alone has little effect on posture when it isn't combined with strengthening. The programs that actually change spinal alignment, reduce pain, and hold up over time are built around making weak muscles stronger, not just loosening tight ones. That doesn't mean stretching is useless. It means it's a supporting player, not the lead. If your posture routine is mostly foam rolling and doorway chest stretches, the research suggests you're leaving the most effective tools on the table.
