It did have a bit of a learning curve, the first few days I was like mmmm...., I don't know. But now, I love it for the efficient work out it gives - my heart rate goes up, my 60 year old body has become quite toned. I do lots of different exercises on it - side lying, planks, side kicks, kneeling, back kicks, so much to do. I like it on the highest. The only thing, I am considering buying another with the flat surface so I can so lots of ab stuff. A great product!
