Here we can see a basic exercise in which the primary goal is to control a single leg landing and ensure good knee alignment. As the saying goes "if you can't stop, you've got no business starting!"
Improper alignment of the ankle, knee, hips and torso can lead to an increased risk of injury through the wrong structures being overloaded multiple times. This kind of drill is designed to teach you to always land in the correct position and to cushion the landing through proper joint alignment. We use it as a warm up drill or a precursor to someone being taught plyometric exercises.
It's also a fantastic screening tool - check out the intentionally bad rep at the end of the video. If every one of your reps looks like this it's a sign that something at the hip or foot isn't doing it's job... Imagine this happening with every foot strike when running!
