is it possible to add a + / - button in the workout screen so its possible to adjust the FTP value without exiting the workout
Hi Norbert, this is in fact a planned feature and we’ll be implementing that this spring.
Hi Norbert,
Just FYI you can do this already in current version of Zwift but it’s a bit more difficult than just pressing +/- keys.
When you’re doing the work out press key “E” and change the FTP value. After hit Workout and you’re all set! It will not affect the workout at all. 
Hope it helps.
Ride On!
Great!!, never dare to touch anything while I’m in a workout. Always worry to loose the data, but I will give it a try if the power on my trainer is off.
Thanks
No problem,
Ride On! :)
