The woman on the left has {argument name="first subject hair" default="shoulder-length wavy reddish-brown hair"}, is smiling happily at the camera, and has a healthy post-workout glow on her skin. The woman on the right has {argument name="second subject hair" default="long dark wet-looking hair"}, and is holding a smartphone in her right hand to capture the photo. Both are wearing matching {argument name="athletic wear color" default="maroon"} athletic sports tops and high-waisted shorts with small white logos, standing close together with one arm around each other. The gym features elegant marble flooring, wooden wall panels, premium fitness equipment, and soft upscale lighting. The overall scene has a fresh, energetic, and positive fitness atmosphere with visible sweat on their skin from a recent workout.
