Realistic Fitness Anatomy Animations

I’m developing a fitness app and now need a library of realistic 3D clips that do three things: reveal individual muscles in action, demonstrate correct posture, and walk users through full exercise motions. The same clean, medically-accurate look has to run through every file so they feel consistent inside the app’s interface.

Scope
• Muscle anatomy sequences – slow, 360-degree turns that fade skin to expose the primary and secondary muscles activated.
• Posture-correction demos – short, loopable clips that show the wrong form first, then the correct alignment from at least two angles.
• Exercise routines – fluid, full-range movements (start–finish–return) that can be triggered as one-shot or set to loop.

Style & Technical Needs
• Photorealistic modelling, lighting, and skin shading; no cartoon elements.
• Neutral, studio-white background so the videos or render passes sit cleanly over any UI.
• 60 fps export in 1080p (4K welcome if your workstation allows).
• Delivery in an app-friendly format such as MP4 for immediate use, plus source animation files (FBX or similar) for future editing.

Acceptance
I will review each animation for anatomical accuracy, smoothness of motion, and colour-coded muscle highlights that match standard kinesiology references before approving final payment.

If you’ve done medical-grade or fitness-oriented animation before, send one sample that best represents that realism and we can lock in the shot list together.
