Engineer Your
Healthiest and
Happiest Lives,
Together.

Helping highly motivated couples optimize their relationship and health by cutting through the muck and sharing what the research says works.

HEY! WE’RE RYAN AND ALEX.

Engineers, coaches, authors, and a husband-wife duo.

We take out the guesswork and follow the science to improve the lives of couples. Why? You’re 3X more likely to stick to health goals if you do it with your partner, and your partner’s habits strongly influence yours.

Our goal is to share the research on how couples can better their fitness, nutrition, and relationship together. We’ve guided thousands of couples to create a life where health is simply a natural by-product of doing what they love, through simple, step-by-step programs.
