Before you start this move, visualize a large square on the floor, and you're standing in the bottom right corner, feet hip-distance apart.
Keeping weight in the heels, bend the knees and squat down. Take a huge jump forward to the top right corner of that imaginary square, landing quietly back into a squat.
Keep going around the square, jumping to the left, jumping back behind you, and jumping to the right. Now you're back where you started.
Continue hopping around the square in this direction for 30 seconds, then reverse your jumps around the square in the opposite direction for another 30 seconds.
