Fitness Tracking

Every REHIT workout will provide a comprehensive set of fitness metrics, including Fitness Score (designed to track VO2max), Peak Power, Maximum Anaerobic Power, Calorie Burn, Energy Output, and Peak Heart Rate.

Your Fitness Score is based on your performance during, and recovery from, an anaerobic sprint. The other fitness tests included in the CAROL Bike workout range measure your Functional Threshold Power (FTP) during an aerobic workout.

CAROL Bike includes Maximum Ramp Tests, in which the target power increases continuously until you reach your personal limits, and FTP tests, in which you either pedal at your limit for 20 minutes or 2×8 minutes.

CAROL Bike will automatically calculate your FTP and Maximum Aerobic Power, and your FTP will be used to set your personal power zones.
