The CAROL Bike: Transformative Cardio in Under 10 Minutes
The CAROL Bike may look like a regular stationary bike, but it’s anything but ordinary. Powered by artificial intelligence, CAROL delivers Reduced Exertion High-Intensity Interval Training (REHIT)—a scientifically validated method that delivers major cardio benefits in just 5 to 9 minutes.
A study published on CAROL’s site reports users saw a 12% increase in VO₂ max over eight weeks, simply by riding three times per week—just two 20-second sprints per session. Other research shows REHIT boosts VO₂ max more efficiently than longer, steady-state exercise, while also improving metabolic markers like insulin sensitivity and blood pressure.
That means in roughly 10% of the time compared to a traditional 45-minute cardio session, users can still reap 90–95% of the heart-pumping benefit. For busy professionals or anyone short on time, CAROL delivers real-world results without the time commitment.
Oxefit: Adaptive Strength Training That Works With Your Body
While free weights like dumbbells offer constant resistance, they don’t adjust to how your muscles move throughout a rep. Oxefit, on the other hand, is an AI-powered strength system that dynamically adjusts resistance to match your unique movement and energy levels.
A core advantage is eccentric overload—Oxefit offers extra resistance during the lowering phase of a lift. According to flywheel training research, this technique enhances muscle growth, strength, and tendon resilience more effectively than traditional resistance alone. In practice, Oxefit can deliver these results safely by reducing joint strain.
Additionally, Oxefit provides real-time metrics—force, balance, muscle symmetry—that empower our coaches to tailor your training precisely. This aligns with findings in Sports Medicine showing that adaptive resistance systems promote better bone density and neuromuscular control compared to standard weights
