You can choose to do your Mental Commands training in two different modes
Animated mode animates the cube the same way every time according to the action being trained ("Live training feedback" toggle OFF).
Live mode moves the cube during the training session according to how well you are activating that command. ("Live training feedback" toggle ON). This mode can be accessed once you have trained a command.
Use the "Live training feedback" toggle on the main training screen to switch between these two modes.
