Things You'll Need
Instructions
Select the "Track & Field" category. Select "Mini-Games" and choose "Javelin."
Position yourself directly in front of the Kinect motion-sensing peripheral. Raise your dominant arm slightly to lift the javelin.
Run in place, lifting your knees up high. When you approach the end of the track and step on the field, angle your body to the left or right.
Hold your arm over your head and swing it forward as hard as you can as if you were pitching a baseball. If you throw hard enough, the javelin breaks the electrical equipment. You get the Circuit Breaker Achievement for doing so.
