Setting timer DOES NOT work! I tried setting my exercise time for 45 secs and the rest time for 30 secs in Garmin Express and Garmin Connect Mobile. Neither would update my FR935 after syncing while connected to my computer or by Bluetooth. I was finally able to edit the times on the watch itself, BUT the rest time will always have the same amount of time that you have set for exercising no matter what you set the rest time for during the workout. For example, my watch says 45 secs exercise, 30 secs rest in settings. I start my workout and exercise for 45 secs and then it starts the rest timer for 45 secs. Verified the settings are for 45 and 30 secs. Please fix.

Perfect idea, but better will be creating workouts and excercises in GCM.

It's a very useful app. Although I have a fénix3 and it really crushes sometimes. Apart from that, it's kind f troublesome to create exercises and workouts on the watch. Maybe if we could create them through the Garmin Mobile app and solve the problem with exercise time and rest time in the app, you would get an awesome app. I'm looking forward to the next update. Thank you very much!

Went through the tedious task of creating all the exercises and workouts on watch and when I try to change the only option through the phone which is the exercise and rest timer it doesn't transfer to the watch. A lot of work for this not to function. Once this is fixed this would be a decent app. Forerunner 235 is the watch I am using.
