Sweet spot sits just below threshold and provides significant aerobic development without the recovery cost of full FTP work. It is particularly useful for time-crunched cyclists who cannot afford long recovery periods between sessions. A typical sweet spot session: 3x15 minutes at 88-93% FTP with 5 minutes recovery. Sweet spot and polarised training are not mutually exclusive — sweet spot can form part of the 20% hard work in a polarised distribution.
