The FreeMotion pattern travels in an Inverted Arch™ to increase range of motion, flexibility and strength. It moves the way you move, naturally. Human movement can only be designed into a machine using an Inverted Arch. The FreeMotion maximizes joint angles for dynamic mobility. Shorter strides fire calves and glutes, mid strides work glutes and quads, and longer strides burn hamstrings. It's training with this natural movement that increases performance in "Sports and Life".
