A sunlit, minimalist home gym corner photographed in soft golden morning light, with a young athletic man seated on a wooden bench, leaning forward with his elbows resting on his knees, catching his breath after a hard leg session. He wears a muted sage-green t-shirt and charcoal shorts, his face turned slightly away from the camera, calm and focused. A matte ceramic dish in the foreground holds a few small, translucent golden softgel capsules, with a glass of water beside it catching the light and casting a soft caustic shadow across a pale oak floor. Behind him, a loaded barbell rests on a squat rack, slightly out of focus, and a tall window pours warm sunlight diagonally across the scene, creating long gentle shadows and a hazy glow. A small potted green plant sits on a shelf at the edge of the frame. The color palette is warm and editorial: cream, soft gold, sage green, pale wood, and charcoal accents. Shallow depth of field, with crisp focus on the capsules and glass in the lower third and a creamy bokeh background. The composition leaves generous negative space on the right side for a headline overlay. The mood is clean, modern, and aspirational, like a high-end wellness magazine or a trendy health journal feature. Shot on a 50mm lens, natural light, fine film grain, subtle matte finish, landscape 16:9 framing.

But there's a twist: soreness didn't improve at all. Here's what the study found, where it falls short, and who might actually care.
