Can I do my Zone 2 rides on the trainer, or is it better to be outside?
The trainer is actually perfect for Zone 2 because there are no stoplights or descents to interrupt your effort. Aim for a steady 60-minute spin where your power stays locked in your target range—for a 250W FTP rider, that's staying between 137W and 187W. It’s the most efficient way to get the work done without any 'junk miles' or coasting.
