Samba improves the flexibility of the body and helps achieve easy movement and lightness. The Samba rolling action teaches the body to be supple. To move lightly, quickly, and smoothly without effort takes study but only at the start. Although considered a good exercise, Samba should be danced smoothly and in a relaxed manner giving the appearance of effortless movement. Sometimes called the South American Waltz, the Samba pulsates to a unique Latin rhythm.
