The project that started it all...

Motus Salus began with ExercisePx. In preparation for presenting a poster at the Society of Behavioral Medicine Conference in April 2026, Spencer Hills created ExercisePx.com as a way to explain the 7 Specifier Framework for Exercise Prescription, a framework shaped by his education and experience in exercise science and clinical behavioral health.

What started as a single program became something more. After building Exercise Px, Spencer realized he wanted a place to continue developing practical ideas, clinical tools, writing, and educational resources beyond one project. Motus Salus was formed to serve as that home.

Motus Salus is an American company with a simple aim: to build useful things and bring grounded ideas into behavioral health. Its work is meant to stay practical, honest, and close to the people it hopes to serve — clinicians, students, researchers, and communities looking for tools that make sense in the real world.
