When the videos play, watch the movements carefully and pay attention to how the person in the video moves. Then have a go at practicing it yourself. Try to copy the movements shown in the video. You can re-watch the videos and practice the skills as often as you need to.
You may find it easier to ask people you know to record themselves doing it from a first person viewpoint. This means that the movements and viewpoints in your videos will closely match what you will see when doing these movements for yourself.
