The Full Story

CADS was created by husband-and-wife team Blaise and Cassie Majewski after years of working directly with athletes, families, schools, and homeschool programs.

Blaise is an athletic performance coach, founder and CEO of Suplify.life, and has spent over a decade developing youth athletes through performance training, nutrition, and mindset coaching. Cassie has over 10 years of experience teaching within homeschool co-ops and educational programs.

​

Together, we saw the same problem everywhere — physical education and athlete development lacked structure, progression, and purpose.

​

"That’s why we created CADS: the Complete Athlete Development System." 

​

CADS is a fully structured physical education and athletic development curriculum designed for homeschool families, co-ops, schools, teams, and youth organizations. It combines athletic training, movement development, mindset, testing, nutrition education, and measurable progression into one complete system.

This is not random activity or basic PE.

​

CADS gives programs a clear roadmap to develop stronger, healthier, more confident athletes through structured training, testing standards, educational resources, instructor tools, and athlete-focused curriculum

.

At the center of the system is The Young Athlete’s Playbook, alongside instructor guides, quizzes, testing systems, QR-code training demonstrations, and mindset development through The Game Within.

​

Since launching, CADS has already helped programs create more engaging PE experiences, improve student participation, build stronger athletic culture, and give families and organizations a system they can confidently implement long term.

We created CADS because we lived the problem ourselves — and built the solution we wished existed.
