A sandwich. Two mattresses. I lie on one of them while the other is covered. The girls tie them together so they won't slide off. The girls are supposed to dance in their shoes on the matress for two songs. It was more like jumping on the matress rather than dancing. They jumped on my legs, back and head. It doesn't look like much, but believe me the girls really gave me a hard workout. I was bending underneath those matresses like a spring and my back hurt for a week. Time: 18,44 min.
