athletic male 3d model

Create a realistic full-body human male character for a game-ready fitness transformation system (NBA 2K-style base avatar). The model must be a neutral athletic male used as the starting point for body sliders (muscle, fat, frame size). Full body visible head to feet, facing forward, symmetrical stance, feet shoulder-width apart, arms slightly away from torso for deformation compatibility. Natural athletic proportions, medium-low body fat, slight muscle definition, realistic anatomy (not stylized or cartoon). Black short hair, neutral face, no expression. Use clean PBR materials, game-ready topology, riggable mesh. The character is shirtless (no top clothing) with blue athletic shorts only, no logos or branding. No robot, mannequin, armor, sci-fi suit, or exaggerated muscles. Avoid cartoon/anime style or distorted anatomy. This is a base model for real-time body transformation sliders in a fitness lab system.
