Exercise Equipment Prototype Development

I'm in need of a seasoned professional who can help me create a prototype for a new fitness workout product based on a resistance band. I have an early prototype that illustrates the design but it is in need of developmental expertise to bring the useable vision to life.

Ideal Skills and Experience:
- Experience in designing fitness equipment
- Strong understanding of user needs across varying fitness levels
- Creativity and problem-solving skills
- Ability to work collaboratively to refine design and functionality
