## Abstract

An exercise assembly simulating the muscular movements of a kayaker includes an elongate seat resiliently mounted on an elongate spine structure supported on adjustable pedestals that are each further resiliently mounted. At the front end an adjustably aligned pivot engages through a U-joint a simulated kayak paddle with the motion of the pivot resisted by restricted orifice cylinders mounted in the spine structure. A generally uniform adjustment arrangement is utilized to conform the assembly to the various users and/or various exercise levels.

## Claims

### Claim 1

An exercise assembly simulating the movements of a kayak on a water surface, comprising in combination:
an elongate spine defined by a front end, a rear end and an upper surface, said front end including a generally transverse edge;
a corresponding mount assembly engaged to support said front and rear ends of said spine, the engagement of a selected one of said mount assemblies to said spine including adjustment means for adjusting the inclination of said spine;
an axle defined by an upper and a lower end pivotally engaged to said front end of said spine including a handle hinged to the upper end thereof;
resistance means operatively connected to said handle for resisting the displacement thereof; and
an elongate seat assembly resiliently mounted on said upper surface of said spine for resiliently supporting a user thereon.

### Claim 2 (depends on 1)

An exercise assembly according to claim 1, wherein:
said resistance means is deployed subjacent said upper surface of said spine for adjustable engagement to said lower end of said axle for providing stabilizing forces to said handle for maintain said user on said seat.

### Claim 3 (depends on 2)

An exercise assembly according to claim 2, further comprising:
a pair of spring urged foot rests adjustably deployed adjacent said transverse edge.

### Claim 4 (depends on 3)

An exercise assembly according to claim 3, further comprising:
a back support selectively engaged to said seat.

### Claim 5 (depends on 2)

An exercise assembly according to claim 2, wherein:
said elongate spine includes a pair of side walls along the lateral edges of said upper surface defining an interior cavity; and
said resistance means is deployed within said interior cavity.

### Claim 6 (depends on 5)

An exercise assembly according to claim 5, wherein:
each said mount assembly further includes a resilient support.

### Claim 7 (depends on 6)

An exercise assembly according to claim 6, further comprising:
a pair of spring urged foot rests adjustably deployed adjacent said transverse edge.

### Claim 8 (depends on 7)

An exercise assembly according to claim 7, further comprising:
a back support selectively engaged to said seat.

### Claim 9

An exercise assembly, comprising in combination:
an elongate spine defined by a front end, a rear end and a top surface;
a mount assembly respectively supporting each said front and rear ends of said spine, a selected one of said mount assemblies being adjustably engaged to said spine for adjusting the inclination thereof;
a pivot shaft defined by an upper and a lower end pivotally engaged to said front end of said spine including a transverse handle hinged to the upper end of said of said pivot shaft;
resistance means connected to the lower end of said pivot shaft for resisting the articulation of said handle; and
an elongate seat assembly pivotally mounted on said upper surface of said spine and resiliently urged for an upward deployment above said upper surface.

### Claim 10 (depends on 9)

An exercise assembly according to claim 9, wherein:
said elongate spine includes a pair of side walls along the lateral edges of said upper surface to define therewith an interior cavity; and
said resistance means is deployed within said interior cavity.

### Claim 11 (depends on 9)

An exercise assembly according to claim 9, wherein:
said resistance means includes a restricted orifice cylinder.

### Claim 12 (depends on 9)

An exercise assembly according to claim 9, wherein:
each said mount assembly further includes a resilient support.

### Claim 13 (depends on 12)

An exercise assembly according to claim 12, further comprising:
a pair of spring biased foot rests adjustably deployed adjacent said transverse edge.

### Claim 14 (depends on 13)

An exercise assembly according to claim 13, further comprising:
a back support selectively engaged to said seat.
