The Complete Indoor Trainer Workout Library: From Recovery Rides to Explosive Power

The indoor trainer is a winter rider’s best friend, but it’s also the training tool most likely to become boring. “I don’t know what to do today” is the number one reason people give up on indoor training.

This library collects eighteen workouts across six categories, from the easiest recovery ride to the most painful VO2max intervals, so you always have a clear training direction. All workouts are marked in % of FTP, so confirm your FTP value first.

How to Use This Workout Library

Power Zone Quick Reference

Zone	Name	FTP%	Perceived Effort
Zone 1	Active Recovery	<55%	Very easy, almost no effort
Zone 2	Aerobic Endurance	56-75%	Can hold a full conversation
Zone 3	Tempo	76-90%	Can speak in short sentences
Zone 4	Lactate Threshold	91-105%	Can only say a few words
Zone 5	VO2max	106-120%	Very painful
Zone 6	Anaerobic	121-150%	Can only hold for tens of seconds
