My wife and I both do a lot of turbo training. We probably do between 5 and 8 hours a week each. I target 100 miles on the turbo a week if time allows. I personally think people who say it's "boring" are just not doing it right. I do Trainer Road programmes on a MacBook Pro. I set it up in horizontal view mode with the data across the bottom of the screen and watch Netflix with bluetooth earplugs. The combination of varied programmes, following the target power and watching Netflix simultaneously keeps it interesting and entertaining. I've been turbo training for a year and have dropped from 86kgs to 72kgs in that time. Its absolutely transformed my health and fitness.
My wife uses Zwift and is a very keen member of their female academy. She is getting very good with her average watts per kilo being around 4.1. She often wins women's races and indeed beats most of the guys in mixed races. She's more competitive than me and the regular racing plus the friendly female Zwift community aspects mean she is addicted to turbo training. Zwift ran a blog on her earlier this year:

Our set up is pretty basic. A non-smart Elite Chrono gel turbo, laptop and a Dyson fan. We use my old Specialized Secteur with a turbo tyre and just move the saddle up and down. I expect our next big purchase will be a Wahoo Kickr for Christmas though! Our set up
