A close up of a woman with different facial expressions

Create a divided image showcasing a personal trainer's contrasting emotions. On one side, depict the trainer with a joyful expression, radiating happiness and positivity. On the other side, portray the same trainer with a pensive or downcast expression, conveying sadness or disappointment. Utilize lighting to emphasize the emotional contrast between the two sides. Maintain consistent background elements to ensure visual continuity. This image should capture the complexity of human emotions and the multifaceted nature of a personal trainer's experiences, while also illustrating their ability to navigate and manage various emotional states.
