Abstract
The present invention provides an exercise apparatus having a frame that extends between a front end and a rear end, and is designed to rest upon a floor surface. The frame supports an inclined rail at an angle of greater than five degrees relative to the floor surface. A seat is slidably secured relative to the rail, and the angle of inclination opposes rearward movement of the seat. A load resistant line means is secured at one end to the seat and at another effective end relative to the frame to further oppose rearward movement of the seat.
Claims4
A method of providing resistance to exercise movement on a rowing simulator using a single elastic cord, comprising the steps of:
- securing a first end of the elastic cord to a simulator rowing bar;
- routing a first intermediate portion of the elastic cord over at least two pulleys and through a first nip arrangement, thereby anchoring a first intermediate length of the elastic cord between the simulator rowing bar and the first nip arrangement;
- routing a second intermediate portion of the elastic cord through a second nip arrangement and over at least one pulley, wherein a slack portion of the elastic cord is defined between the first nip arrangement and the second nip arrangement, and the second intermediate portion terminates in a second end of the elastic cord;
- and
- securing the second end of the elastic cord to a seat, thereby anchoring a second intermediate length of the elastic cord between the second nip arrangement and the seat.
An exercise apparatus, comprising:
- a frame having a front end and a rear end, and designed to rest upon a floor surface;
- an inclined rail supported above the floor surface by said frame, wherein said inclined rail defines an angle of greater than five degrees relative to the floor surface;
- a seat slidably secured relative to said rail, wherein the angle of said rail opposes rearward movement of said seat;
- a load resistant line means secured at one end to said seat and secured at another effective end to said frame wherein said load resistant line means opposes rearward movement of said seat;
- a retractable hand bar positioned proximate said front end of said frame;
- and
- a second load resistant line means secured at one end to said hand bar secured at another effective end to said frame, wherein said second load resistant line means opposes rearward movement of said hand bar;
- wherein said load resistant line means and said second load resistant line means are integral portions of a single elastic cord.
