Title: Great Product, but challenging
Review: This is a great product to get in shape. I have Rheumatoid Arthritis in my knee so I was looking for something that was low-impact. The video is challenging, its difficult to follow along if you are just learning how to use the wave, but after a lot of practice, you get the hang of it and it truly is a great workout. It has greatly improved my posture and balance.
