The UKBF 16-week Aerobic Base Plan follows a periodization strategy to maximize results, with CP (Critical Power) testing at the start, middle, and end to monitor progress. The plan is flexible, allowing athletes to adjust sessions based on their availability and commitments. Training is conducted using either a percentage of FTP or the RPE (Rate of Perceived Exertion) scale, depending on whether athletes have a power meter. Regular testing ensures the accuracy of training zones and helps optimize each session for improved fitness over time.
