To manually adjust Smart Control trainer resistance with the Fit app do the following:
- When connected to the Smart Control with the Fit app, choose a FREE RIDE workout.
- You'll be taken through a 10-minute warmup and calibration. After that the Free Ride workout will begin.
- While riding the FREE RIDE workout select the menu on the bottom left of the screen. You'll see a SETTINGS menu item.
- 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.
