A realistic vertical video featuring a real human male model, filmed against a pure black studio background.
The camera is static, side-profile view (left-facing), full upper body visible from head to mid-thigh.
The same person remains consistent throughout the entire video.
Scene progression happens smoothly within one continuous shot:
Phase 1 – Poor posture:
The man starts with forward head posture and rounded shoulders.
His neck leans forward, upper back slightly hunched, chest collapsed, posture visibly compressed.
Muscles appear tense but inactive, body looks shorter and misaligned.
Phase 2 – Transition:
Over time, his shoulders slowly roll back, chest begins to open.
The spine gradually straightens vertebra by vertebra.
The head lifts and aligns naturally over the shoulders.
Movement is slow, controlled, and realistic, driven by muscular engagement, not snapping.
Phase 3 – Correct posture:
He finishes standing tall with a neutral spine, shoulders back and down, chest open, neck elongated.
The body appears visibly taller and more aligned compared to the beginning.
Posture looks relaxed, strong, and balanced, not exaggerated.
Lighting is soft and directional, highlighting muscle definition and posture changes without dramatic effects.
Realistic skin texture, natural muscle movement, anatomically accurate proportions.
No text, no subtitles, no graphics, no measurement lines, no overlays, no logos.
Ultra-realistic, TikTok-native style, vertical 9:16, clean studio realism.
