Practising our Javlin Throw.

Greg taught us how to throw the vortex and the foam javlin. 

The skills you need to master are:
Use your whole body to twist releasing the energy from your legs through to your wrist.  This will give you a powerful throw.

We had to run after the vortex each time we made a throw.  It was tiring in the sun.

Make sure you place your hands in the correct place.
