studio portrait of Phoenix, a muscular gym influencer in his late 20s, sitting on a gym bench, facing the camera directly. He is framed in a medium shot, focusing on his upper body. He wears a sleek black workout vest that showcases his well-developed shoulders, chest, and arms. The background is a dark, minimalist gym setting with soft, out-of-focus lighting. Dramatic studio lighting with a key light from the front-left creates sharp definition on his muscles and a slight rim light from the right separates him from the background. Photorealistic, hyper-detailed, 8K resolution, shot on a Sony A1 with a 85mm f/1.2 lens. Professional athlete photoshoot.
