First, if your athlete is busy following your training schedule then you will need to get their attention in the 3D view. 

This game takes place in the Gym if you move your mouse curser across the blue training mat, the Go icon will appear.

Click on the Go icon and four coloured buttons will appear at the bottom of the screen.  The "On Your Marks" message will come up then the game will start.

The idea of this game is very simple, the four buttons at the bottom of the screen will light up in sequence, then you must click on the buttons with the same sequence showed by the lights.  Each time you complete a sequence the "On Your Marks" message will reappear and a new sequence will start with the light sequences becoming progressively faster and harder as you complete them. 

The yellow box in the top right corner shows two times.  The top number is time remaining to complete the current sequence of lights, the bottom number indicates how many lights there are to each sequence.  When a sequence of lights starts the bottom number will be at 0 and will count up each light that shows, as you click on the lights the number will then go down back to 0 as you complete the sequence.  

Each coloured button represents a set of aerobic exercises for your athlete and if you complete a sequence correctly you are rewarded by being able to watch him/her go through the sequence in training.

If you do not get the sequence right the game will finish.  If you wish to stop the game at any time, click on the red X in the bottom right corner of your screen.
