The equipment is based on the masses used for the original Reformer and has been upgraded with Balanced Body's unparalleled craftsmanship and high quality materials. One of the smoothest and quietest rides on the market, the CenterLine Reformer features soft-textured carriage wheels that provide increased ride resistance. This facilitates and improves the balance of joint and core activity, as does the smooth pivoting of the Leather and Wood Handles.
