Just press your trackpad/joystick into the direction want to go and then you start jogging on the spot SO YOUR HEAD MOVES UP AND DOWN. You don't even have to move your arms!
To sprint you will have to move your arms as well as your head!
If you play the game this way it will be fun!
If you try to move solely with your arms the game will just feel awkward!
IMPORTANT NOTE: You can run pretty fast by just moving your head !
