Simply, the Reformer is a machine which is used to do Pilates, it involves a
moveable carriage and springs and a pulley system which provide resistance
and allows for a large range of movement, more so than on a Mat. Its origins
date back to WWI when Joseph Pilates was working in an infirmary for
wounded soldiers, he rigged up a pulley system to their hospital beds which
allowed them to do some resistance work and this then evolved into a very
modern (and popular) apparatus today!
While it enables us to do most of the Pilates exercises we can do on a Mat, it
also allows for a whole range of new exercises that can only be done on the
machine. The set up of the Reformer also makes it easier to hold our correct
position compared to the Mat.
