Just a couple of ideas for the future versions of the Training Gym:
-As there is already a possibility to change the User settings (Age, name, etc.) by using Training Gym, I think it would be very nice to be able to access all the settings (Display, Lap, GPS...) from Training Gym.
You could have e.g. different sets for configurations saved on your PC e.g. for Cycling, Walking, short track running, racing... and just upload to the device and run!
-It would be very nice to be able to build up routes in Training Gym (graphically)and just upload them to the device.
