Query: Terrific, highly recommended!

I got this for my mum on mother's day and got a rave review. She's done yoga and pilates in the past but says this particular yoga is great. The first couple of times you try it, it is quite challenging and will make you dizzy, possibly even nauseous. But that awkwardness (which lasts a whole day, may i add) will dissipate and once you ease into it, thats when you'll start to experience it properly. The end result is a stronger back and spine, and alot more energy and confidence.A great product, highly recommended!
