Frequently asked questions

What zone should I train in most?

Z2 (endurance, 56-75% FTP) for the majority of your volume — typically 70-80% of training time. This builds aerobic base and mitochondrial density without excessive fatigue. Higher zones (Z4-Z5) are the remaining 20-30%, used for targeted adaptations.

What is sweet spot training?

Sweet spot training (88-93% FTP, between Z3 and Z4) maximises the ratio of training stress to recovery. It's harder than pure tempo but easier than threshold, making it very time-efficient for FTP improvement.
