CEO & co-founder of CAROL, Ulrich Dempfle graduated in mechanical engineering from Germany’s leading tech university. After working with Europe’s top automotive manufacturers, Ulrich moved to London where he pioneered AI healthcare initiatives, optimizing operational efficiency for the National Health Service.

Watching a BBC documentary on reduced exertion high-intensity training (REHIT), Ulrich realized its potential as the ultimate cardio hack. The problem? REHIT was only possible in a lab setting. The solution? Ulrich co-founded CAROL and partnered with the world’s leading exercise researchers to take REHIT out of the lab. 40 prototypes later, the world’s only REHIT exercise bike was launched. CAROL improved Ulrich’s cardio health by 50%. He also lost 10kg and dropped his elevated blood pressure. This opened Ulrich’s eyes to the power of biohacking. From cold showers, daylight exposure and intermittent fasting to meditation, blue light avoidance and sleep tracking, Ulrich now uses the latest science to optimize his health.
