Create a high-resolution image set in a modern, well-equipped gym

Create a high-resolution image set in a modern, well-equipped gym. At the center of the scene is a personal trainer, standing confidently with a well-defined, muscular body. He should be in his mid-30s, with short, dark hair and a friendly yet focused expression. The trainer wears a fitted sleeveless athletic shirt and shorts, showcasing his toned arms and legs. In the background, capture a group of diverse students engaged in various exercises. They should be in different stages of their workouts: some lifting weights, others doing cardio on treadmills, and a few stretching on mats. The students should reflect a range of fitness levels and body types to highlight inclusivity and the trainer's ability to work with different individuals. The gym should have a lively atmosphere, with bright lighting and a clean, organized layout. Include details like exercise equipment (dumbbells, barbells, kettlebells), mirrors on the walls, and motivational posters to enhance the authenticity of the setting. The trainer should be positioned near a piece of gym equipment, perhaps demonstrating a proper lifting technique to one of the students. Ensure the scene conveys a sense of energy, motivation, and the supportive environment the trainer fosters with his students.
