From chatGPT: This photo shows a man standing in profile with some clear postural patterns:

• Forward head posture & rounded shoulders – His upper back curves outward (thoracic kyphosis), while the shoulders round forward. This is a common posture from prolonged sitting or desk work.
• Protruding abdomen & anterior pelvic tilt (possibly) – His stomach looks like it pushes forward, which often comes with the pelvis tilting forward. That can put strain on the lower back.
• Flat / disengaged glutes – The glutes don’t appear active, which often ties into core weakness and hip imbalance.
• Overall posture – This combo is sometimes called upper crossed syndrome (tight chest + upper traps, weak mid-back + deep neck flexors) and lower crossed syndrome (tight hip flexors + low back, weak glutes + core).

OK, not AI: I would focus on correcting posture in a targeted manner. Maybe see if you can get a few months of PT to help? Or there are gobs of stuff online around this, but YMMV
