Is the idea of indoor cycling workouts specifically designed for improving endurance a myth, and are we just chasing a fad thats driven by the likes of Zwift and Peloton, or is there actual science behind the notion that we can significantly improve our endurance by following a structured indoor training program? I mean, think about it, arent we just pedaling in a room, going nowhere, and getting bored out of our minds, or are there certain specific workouts and training techniques that can actually make a tangible difference in our outdoor performance? Ive seen some of these indoor workouts claiming to improve endurance by up to 20% in just a few weeks, which sounds like a pretty tall order, so Id love to hear from those who have experience with indoor training - what are the most effective workouts, and what are the actual benefits of indoor cycling when it comes to endurance?
