1. Set a series of cones out in a cross formation. (see diagram right)
2. Run backwards to the center cone, side step to the right cone (or your left if you are performing the drill), side step back to the centre cone still facing the same way.
3. At the center cone turn and sprint forward to the end cone. Now run back to the center cone, side step to the left, side step back to the center, then turn and sprint back to the start.
4. Phew! Sounds complicated - it's not - the diagram explains it quicker than I can!
