REVVO

Revvo is a stationary bike that makes it easy to accurately measure gold standard indicators of fitness, wellness and health: VO2Max, Recovery and Endurance. VO2Max is the single best indicator of physical fitness and heart health but you need to wear a face mask, pay $150 and spend ~two hours to measure it in a lab. Revvo guides you through an ~15 minute fitness test (while analyzing heart rate and cycling power/watts) to measure VO2Max and the other vital metrics - at lab quality but without using face masks.
