Place ten cones on the ground in front of you, equidistant apart, as shown in the diagram.
Start next to cone one facing cone 6.
With your feet close together and your hands on your hips, perform three two-footed jumps on the spot trying to jump as high as possible with as little time in contact with the ground as possible.
Continue jumping as you travel in a forward direction to cone two, then on to cones nine, four, seven and six.
Return to the start and repeat.
