You’re only as old as you move

Stay limber for life.

The next generation wearable for personal mobility

Beat age, adapt

It’s not the strongest of the species who survives, nor the most intelligent. It is the one who is most adaptable to change.”

—Charles Darwin

Adaptive intelligence

Powered by advanced motion sensing technology, limber uses cutting-edge neuroscience and techniques from elite sports to train your adaptive intelligence.

Built by the best for the best

Rachael and Stephanie were early adopters of wearables and excited about the technology helping people to adapt to change as they age.

Backed by Serena Williams, Techstars, StartX, MassRobotics, trusted by clinicians from Kaiser, Cedars Sinai & Shirley Ryan, they built limber.

Stay limber for life.
