This is an idea that was raised by @HRS in the Future of Longevity Impact Roadmap Community: A treatment or biomedical device that can replicate the beneficial effects of exercise, without the user having to exert her body.
Stipulations: The winning team will come up with a safe treatment or biomedical device that will provide the benefits of physical exercise without the need for free time, willpower, expert guidance or good health.
Importance: Physical exercise is well accepted as positively impacting both lifespan and healthspan. However, it requires willpower, time, experience or guidance, and general good health from the get-go. It is therefore difficult to massively scale the benefits of exercise. This XPRIZE will ensure that everyone can enjoy the health benefits of exercise.
