Your camera will detect your movements

You'll set this up just before starting the test.

Remember the target color

First, the whole screen flashes one color for a moment. That is the color to look for.

Move the limb closest to that color

The limb can move to the side, up, or down.

Movements toward the camera aren't registered — make sure to kick to the side, not forward

Expect to get faster

Almost everyone speeds up over their first two or three tests while getting used to it, so don't worry about a slow first try.
