I've created a dynamic webpage with a red and black color scheme that features a 3D gymnast model that changes poses as you scroll down the page. The website includes:

1. Hero Section: A bold introduction with red accents and a call-to-action button.

2. 3D Gymnast Model:

   • Positioned on the left side of the page (stays fixed as you scroll)
   • Changes poses based on scroll position (standing, split, handstand, bridge)
   • Uses React Three Fiber for 3D rendering

3. Gym Information Sections:

   • About Our Gym: Overview of the facility and credentials
   • Training Methods: Detailed explanation of the training approach
   • Championship Results: Showcasing achievements and medals
   • Contact Form: For inquiries and sign-ups

4. Design Elements:

   • Red and black color scheme throughout
   • Gradient backgrounds
   • Responsive layout that works on mobile and desktop
   • Smooth scrolling animations

The 3D model uses a placeholder (the built-in duck model) since we don't have a gymnast model available, but the pose changes are implemented to demonstrate the concept. In a real implementation, you would replace this with an actual gymnast model.

To view this website, you can click the preview button above or add it to your codebase using the "add to codebase" button.

I'll update the website to use the bodybuilder 3D model from Sketchfab with a transparent background. Since we're using an external 3D model from Sketchfab, I'll integrate it directly into our page.

I've updated the website to use the Sketchfab bodybuilder 3D model with a transparent background. The model will now display on the side of the page as you scroll through the content. Here are the key changes:

1. Integrated Sketchfab Model:

   • Embedded the bodybuilder 3D model directly from Sketchfab
   • Set up transparent background by using the Sketchfab embed parameters
   • The model will be visible against any background

2. Updated Poses:

   • Changed the poses to bodybuilding-specific ones:

     • Standing
     • Front Double Biceps
     • Side Chest
     • Back Lat Spread
   • The model will change "poses" as you scroll through different sections

3. Content Updates:

   • Changed all gymnastics references to bodybuilding

   • Updated training methods to focus on:

     • Hypertrophy Training
     • Periodized Programming
     • Nutrition Optimization
     • Posing & Competition Prep
   • Updated achievements to reflect bodybuilding competitions

4. Visual Style:

   • Maintained the red and black color scheme
   • Kept the responsive layout that works on all devices

The Sketchfab embed allows the 3D model to be displayed with a transparent background, so the bodybuilder will appear to float on the page while showing off different muscle poses as you scroll through the content.
