Description
In this episode, Angela sits down with Ulrich Dempfle, co-founder and CEO of CAROL Bike, to uncover the science and innovation behind one of the most time-efficient ways to boost VO₂ max, metabolic health, and brain function.
Ulrich explains why VO₂ max is the most important marker for longevity, how it declines without training, and how short, AI-guided REHIT sprints boost mitochondria, BDNF (brain-derived neurotrophic factor), and cardiovascular fitness in just minutes.
He also breaks down how Reduced-Exertion High-Intensity Interval Training (REHIT) works, why traditional zone 2 training doesn’t work for everyone, and how gamification and real-time performance data make staying consistent easier than ever.
