The mark consists of a circular design with the word PILATES in large block letters in a curve at the top of the drawing. Directly underneath PILATES is the number 600 in smaller font size. In the center of the drawing are two figures, male and female back to back, sitting on the ground with front leg bent and opposite arm bending to touch their knees, and with front arms extended out and back legs extended out while they are sitting on the ground. Underneath the figures is the word FLOW in block lettering the same size as the word PILATES. On either side of the drawing are two spring cables from a Reformer bed, curved around each side of the design.
Color is not claimed as a feature of the mark.
