Training zones based on power instead of heart rate – how useful is this really?
More and more road cyclists manage their training with a power meter and FTP instead of relying on heart rate alone.

Power-based training is modern and structured but requires expensive equipment. The most effective approach is usually a combination: train by power and use heart rate to check whether the workload matches your current fitness.
