Edit the reference photo: the same man, same gym, same camera angle, same black shorts and blue sneakers, same red anatomical glow on the thigh and glutes. Change only the pose: he is now at the TOP of a stationary lunge (split squat): standing tall with both legs almost straight, front foot and back foot in exactly the same floor positions as in the reference, torso upright, arms stretched forward for balance. Full body and head in frame, square image.
