This is a series of three videos I have made that would be a really good start to someone new to yoga. Once you have learned the technique in the first video, you can just do the practise in the second and third videos.
This is a classic physical practise practised with variations by Yogi's all over the world. It's good to learn so that you can just flow with it. Watch and practise at the same time till you get the hang of it.
It's important to spend some time relaxing in Savasana after doing a physical practise. This particular practise increases body awareness and improves left right balance. It's a great meditative practise to use with children who are learning cross body exercises.
