I have bought this product to top up my belly dancing lessons. Sadie explains which muscles to use very well and she shows each movement one by one in this video, so you practise with her and get memory muscle. I would recommend this video to a beginner or improver who also does a lot of practise. Some moves are a bit harder than the others but Sadie says which ones thay are so you will know not to expect too much from yourself at once. I also highly recommend warm up session which helps with the flexibility.
The only thing I can say that the bonus session dancing includes a lot of moves which are not taught in the techniques sessions. I suppose it points the challenge ahead.
Very pleased with the purchase and it definitely improved my belly dancing.
