Abstract

A compact portable abdominal exercise apparatus comprising a first member that concentrically slides in a second member, and resistance is provided by elastic attached between the distal end of the first member and the distal end of the second member. Handles position the user in an ergonomically neutral position that requires a user to crunch straight downward for the first member to slide properly within the second member. The straight downward crunching motion requires flexion of the user'"'"'s lower vertebra column, thereby isolating the abdominal muscles from the hip flexors and back muscles. Molded covers protect the user from moving parts associated with the connector assembly. The elastic members can be quickly changed by the user.

Claims

1. A compact abdominal exercise apparatus comprising:

(a) a lower body support adapted to engage a portion of the human body below the abdomen;

(b) an upper body support adapted to engage a portion of the human body above the abdomen; and

(c) an upper body support and lower body support connector assembly comprising;

a first member having a first member proximal end and a first member distal end;

a second member having a second member proximal end and a second member distal end;

a first elastic anchor member attached to said first member;

a second elastic anchor member attached to said second member;

said lower body support attached to the proximal end of one of said first member and said second member and said upper body support attached to the proximal end of the other of said first member and said second member; and

said first member slideably fitting within said second member with said first elastic anchor member longitudinally slideable within said first member and located farther from the one of said lower body support and said upper body support to which it is attached than the one of said lower body support and said upper body support to which it is not attached.

2. A compact abdominal exercise apparatus as in claim 1 and further including a first elastic member connected between said first elastic anchor member and said second elastic anchor member.

3. A compact abdominal exercise apparatus as in claim 2 wherein said first elastic member comprises an elastic cord.

4. A compact abdominal exercise apparatus as in claim 2 wherein said first elastic member comprises an elastic band.

5. A compact abdominal exercise apparatus as in claim 2 and further including, a second elastic member connectable between said first elastic anchor member and said second elastic anchor member.

6. A compact abdominal exercise apparatus as in claim 5 wherein said elastic members comprise elastic cords.

7. A compact abdominal exercise apparatus as in claim 1 and further including a protective cover substantially enclosing said connector assembly.

8. A compact abdominal exercise apparatus as in claim 7 and further including an elastic member connectable between said first elastic anchor member and said second elastic anchor member, and wherein said protective cover includes an opening providing access to said elastic member.

9. A compact abdominal exercise apparatus as in claim 7 wherein said protective cover assembly is padded.

10. A compact abdominal exercise apparatus as in claim 1 wherein said lower body support is adapted to engage the front portion of the human thigh.

11. A compact abdominal exercise apparatus as in claim 1 wherein said upper body support is adapted to engage a human hand.

12. A compact abdominal exercise apparatus comprising:

(a) a forward thigh member adapted to engage the forward portion of the human thigh;

b) an upper body member adapted to engage a portion of the body above the abdomen;

(c) a plurality of resilient cords;

(d) a lower body cord anchor;

(e) an upper body cord anchor;

(f) a constraint assembly connecting said lower body member and said upper body member;

said constraint assembly permitting relative motion of said lower body member and said upper body member in a first direction along a line connecting said lower body member and said upper body member and preventing relative motion of said lower body member and said upper body member in directions perpendicular to said first direction;

said constraint assembly including;

a lower body support member rigidly connecting said lower body member and said lower body cord anchor; and

an upper body support member rigidly connecting said upper body member and said upper body cord anchor;

(g) said lower body cord anchor located closer to said upper body member than said upper body cord anchor; and

(h) said resilient cords connectable between said lower body cord anchor and said upper body cord anchor.

13. A compact abdominal exercise apparatus as in claim 12 and further including a protective cover substantially enclosing said constraint assembly and said cord anchors, said protective cover including an opening for accessing said cords.

14. A compact abdominal exercise apparatus comprising:

(a) a lower body member adapted to engage a portion of the human body below the abdomen;

(b) an upper body member adapted to engage a portion of the human body above the abdomen;

(c) a constraint assembly connecting said lower body member and said upper body member, said constraint assembly permitting relative motion of said lower body member and said upper body member in a first direction along a line connecting said lower body member and said upper body member and preventing relative motion of said lower body member and said upper body member in directions perpendicular to said first direction, said constraint assembly including a resistance mechanism resisting but not preventing relative motion of said lower body member and said upper body member in said first direction; and

(d) a protective cover substantially enclosing said constraint assembly.

15. A compact abdominal exercise apparatus as in claim 14 wherein said constraint assembly includes a resistance adjuster and said cover includes an opening providing access to said resistance adjuster.

16. A compact abdominal exercise apparatus as in claim 14 wherein said cover comprises a first piece and a second piece and a fastener for fastening said first piece to said second piece.

17. A compact abdominal exercise apparatus as in claim 14 wherein said cover comprises molded plastic.

18. A method for exercising abdominal muscles wherein a user grasps the handles of a compact abdominal exercise apparatus comprising a connector assembly, said connector assembly comprising a first member attached to said handles and slideably fitting within a second member adapted to fit the users lap, said method comprising:

compressing said first member towards said second member and stopping at a first position; and

pausing said compressing for a period of time.

19. A method for exercising as in claim 18 and further including:

compressing said first member towards said second member and stopping at a second position;

pausing said compressing for a period of time; and

releasing said compressing.
