Are high-volume, low-intensity Zwift workouts a waste of time for serious cyclists who are trying to maintain or improve their power output during the winter months? Ive seen a lot of riders racking up huge mileage on Zwift, but is this really translating to improved performance on the road? Or are they just burning time and energy that could be better spent on more focused, high-intensity interval training? Whats the real benefit of putting in 20 hours a week on Zwift if youre not pushing yourself to new levels of intensity? Is it just a false sense of security, or is there actual science behind the idea that high-volume, low-intensity training is beneficial for cyclists?
