How do i manually control resistance with the Fit app?

To manually adjust Smart Control trainer resistance with the Fit app do the following:

1. When connected to the Smart Control with the Fit app, choose a FREE RIDE workout.
2. You'll be taken through a 10-minute warmup and calibration. After that the Free Ride workout will begin.
3. While riding the FREE RIDE workout select the menu on the bottom left of the screen. You'll see a SETTINGS menu item.
4. Open SETTINGS and use the "TRAINER FLUID LEVEL" slider. Each percentage of adjustment adds approximately one degree of virtual slope to the simulated fluid power curve. See screen capture attached.
