CAROL Bike

Time is the only non-renewable resource you have. 

While the fitness industry has spent decades convincing everyone that more is better, more miles, more hours, and more sweat, the reality of cellular adaptation tells a different story. 

True metabolic resilience isn’t found in the duration of the effort, but in the precision of the stimulus.

CAROL Bike is the world’s first AI-optimized exercise bike, and it’s a masterclass in the science of “time-collapsed” training.

By utilizing REHIT (Reduced Exertion High-Intensity Interval Training), CAROL delivers the physiological equivalent of a 45-minute jog in just 8 minutes and 40 seconds. 

This isn’t a “hack” in the sense of a shortcut; it is a clinical application of biological signaling. 

The bike’s AI-driven resistance is tailored to your specific power output in real-time, forcing your body to deplete muscle glycogen and trigger a massive surge in VO2 max and insulin sensitivity.

Here is what sets CAROL apart for the elite performer:

• AI-optimized resistance: Standard bikes rely on manual tension. CAROL’s AI analyzes every pedal stroke to apply the exact resistance required to reach your “peak power” during two 20-second sprints, ensuring you hit the threshold for maximum adaptation every single time.
• Superior VO2 max gains: Research shows that CAROL’s specific REHIT protocol is twice as effective at improving cardiorespiratory fitness as traditional moderate-intensity exercise.

CAROL provides a solution for maintaining elite cardiovascular health *without* the massive time tax.
