Coggan Power Zones

Zone	Name	% FTP	Watts	Description
1	Active Recovery	< 55%	< 146 W	Very easy, recovery riding
2	Endurance	56–75%	149–200 W	Long steady rides, fat burning
3	Tempo	76–90%	202–239 W	Comfortably hard, sustained effort
4	Lactate Threshold	91–105%	242–279 W	At or near threshold, race pace
5	VO₂max	106–120%	282–319 W	Hard intervals, VO₂max improvement
6	Anaerobic	121–150%	322–399 W	Very short, very hard efforts
7	Neuromuscular	> 150%	> 399 W	Sprints, maximum force efforts

Log every ride and let FlipMP automatically detect your power curve, track FTP changes over time, and adjust your zones dynamically.
