realistic male 3d model

Create a realistic 3D human male seated on a stable chair, performing a physical therapy leg exercise. The character should wear fitness clothing (sports t-shirt, shorts, sneakers). Body proportions should be anatomically correct. Arms resting naturally or holding the chair for balance. Legs lifting forward one by one like a knee extension exercise. Neutral facial expression, focused look. Lighting clean and neutral. Clear details in muscles and joints, smooth realistic skin texture. High-quality animation-ready topology, clean mesh, no artifacts. Chair should look sturdy and minimal. T-pose alternative pose also included for rigging. View full body with no clipping. Clean background.
