Adjustable reformer
An adjustable reformer for exercising is provided. The reformer includes a frame, a carriage slidably mounted to the horizontal frame, and at least one resistance element connected to the carriage. A cord connects the carriage to at least one lower guide and at least one upper guide. Pulling the cord causes movement of the carriage along the frame against resistance provided by the resistance element. The guides can be height adjustable. The reformer can include a cord-length adjustment system. Related methods of exercise are also provided.

2. The reformer of claim 1 , wherein each rail slot is formed on a laterally inboard face of a respective rail and is open upwardly for sliding the spring connector plate downwardly into a respective pair of rail slots.
3. The reformer of claim 1 , wherein each protrusion is sized and shaped to facilitate lifting of a respective end of the spring connector plate from a respective rail slot.
4. The reformer of claim 1 , wherein each protrusion is rounded.
5. The reformer of claim 1 , wherein each protrusion comprises a knob.
6. The reformer of claim 1 , wherein the axial plate position of the spring connector plate is adjustable for adjusting the spring resistance.
7. The reformer of claim 1 , wherein the spring connector plate has a first face directed toward the carriage and a second face axially opposite the first face and directed toward the frame second end, and wherein the spring slots are open to the first and second faces of the spring connector plate.
8. The reformer of claim 1 , wherein the spring slots are formed integrally in the upper edge of the spring connector plate.
9. An adjustable reformer, comprising:
a) a frame extending horizontally along a frame axis between a frame first end and a frame second end of the frame, the frame including a pair of rails spaced laterally apart from each other and extending along the frame axis between the frame first and second ends;
b) a carriage slidably mounted to the pair of rails so as to reciprocate along the frame axis between the frame first and second ends;
c) a spring connector plate extending laterally across the frame between the first and second rails adjacent the frame second end, the spring connector plate adjustably mounted to the frame for adjusting an axial plate position of the spring connector plate relative to the frame second end, and the spring connector plate having a plurality of spring slots open to, and spaced laterally apart from each other along, an upper edge of the spring connector plate; and
d) a plurality of springs for connecting the carriage to the spring connector plate to bias the carriage toward a carriage position between the spring connector plate and the frame first end, each spring having a spring first end connected to the carriage and a spring second end removably receivable in a respective spring slot of the spring connector plate to facilitate connection and disconnection of respective springs to the spring connector plate for adjusting spring resistance,
wherein the spring connector plate has a first face directed toward the carriage and a second face axially opposite the first face and directed toward the frame second end, and the spring slots are open to the first and second faces of the spring connector plate, and
wherein the spring second end of each spring has a neck portion slidable downwardly into a respective spring slot and a head portion larger than the neck and the respective spring slot for bearing against the second face of the spring connector plate when the neck portion is in the respective spring slot to axially fix the spring second end relative to the spring connector plate.
10. The reformer of claim 9 , wherein the head portion comprises a knob.
11. The reformer of claim 9 , wherein each spring is held in lateral alignment with a respective spring slot.
12. The reformer of claim 9 , wherein each spring has an extendible spring body between the spring first end and the spring second end, and the carriage includes a plurality of spring retainers on the underside of the carriage, each spring retainer supporting a respective spring body above a ground surface when the spring second end is disconnected from the spring connector plate, while accommodating extension and contraction of the spring body when the spring second end is connected to the spring connector plate.
13. The reformer of claim 12 , wherein the carriage has a carriage first end toward the frame first end and a carriage second end axially opposite the carriage first end and positioned toward the frame second end, and wherein the spring first end is secured to an underside of the carriage between the carriage first and second ends, and the plurality of spring retainers are adjacent the carriage second end.
14. The reformer of claim 12 , wherein the plurality of spring retainers project downwardly from the underside of the carriage.
15. The reformer of claim 12 , wherein each spring retainer comprises an opening through which a respective spring body passes.
16. The reformer of claim 9 , wherein the spring connector plate is repositionable to any one of a plurality of different axial positions along the pair of rails, each of the different axial positions defined by a respective pair of rail slots in the pair of rails for removably receiving laterally opposed ends of the spring connector plate.
17. The reformer of claim 16 , wherein each rail slot is formed on a laterally inboard face of a respective rail and is open upwardly for sliding the spring connector plate downwardly into a respective pair of rail slots.
