Could not find this term in the Search. I just started using it this week. So awesome. Makes the indoor workouts focused, structured and fun. You can do Power based workouts without a Power Meter. I can project the workout on my flat screen and watch videos with the ride data on the bottom. I am now using one of their base plans based on my first ever FTP test I did on their program.

I also use them. The 8 minute test is insane. It made me realize I'm not fit

Peripedal is similar but will be a one time fee rather than an on going monthly cost. Currently in Beta but works well.

And works only with Windows .........

I thought developers were getting smarter than that nowadays.
