From a standing position, take a big step with your right foot and sweep your left foot behind and across your body. Your left arm comes across the body as well while keeping your back straight.
Come back to standing.
Repeat on the other side, this time starting by taking a big step with your left foot, then sweeping right foot and arm across the body.
Add a hop for some extra fun!
Do this for 45 seconds, rest, then another 45 seconds.
