The Seal is a Classical Pilates exercise near the end of the Mat order. The rhythmic rolling gives the spine a much needed massage. Begin by sitting on the Mat with your legs bent. Touch both heels together and dive your hands between your legs, holding on to the outside of each heel, lifting feet slightly off the Mat. Balancing on the sacrum, roll back on to the shoulders and clap feet three times using control, then roll up onto the sacrum and clap feet three times. Beginners can leave out the claps.
