AI Technical Summary

Benefits of technology

[0012] The device strengthens abdominal muscles isolatedly without any undesired stress on the spine, i.e. the press arm is not loaded when it is lifted (upward movement) and thus no extra stress is applied to the spine as it is e.g. when lifting a weight. The device according to the invention does not use an eccentric abdominal muscles contraction, which eliminates onset muscle soreness and unhealthy stress on the spine of the users.

Problems solved by technology

When these muscles are in poor condition, additional stress is applied to the spine as it supports the body and back injury or pain is more likely.
Exercises for strengthening the abdominal muscles range from simple sit ups and crunches, that requires almost no exercising device, to complex, expensive machines which are strengthening abdominal muscles in seated or laying in supine position.
Traditional sit-ups (where feet are anchored and the upper body is lifted from a reclining position) do not work correct muscles, so the abdominal muscles that support the spine remain weak.
However, substitution of muscles during use of these machines is common and hinders true abdominal strengthening of abdominal muscles.

Embodiment Construction

[0020] The exercise device for strengthening of abdominal muscles according to FIG. 1 comprises a collapsible frame 1 having a holder 1a of a resistance mechanism 5, rear base 1b and front base 1c. All parts of the collapsible frame 1 are connected by central pivotal joint 2 and their position is secured by pin 3. Press arm 4 is, on its one end, rotatively mounted on the holder 1a of the resistance mechanism. Resistance mechanism 5 is connected to the press arm 4. Resistance mechanism 5, in this embodiment, consists of a hydraulic system with adjustable resistance and is connected from the top side of the press arm 4, i.e. resistance mechanism 5 is attached over the pivotal mount 40 of the press arm 4.

[0021] In another embodiment, resistance mechanism 5 may be attached to the frame 1 and press arm 4 from the bottom of the pivotal mount 40, i.e. the resistance mechanism 5 is attached to the press arm 4 from a position under the pivotal mount 40 (See FIG. 4 for a side view of a solid...

Abstract

An exercise device for strengthening of abdominal muscles employing a resistance mechanism is disclosed.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This claims priority from patent application No. PP 136-2006, filed Dec. 22, 2005 in the Slovak Republic, incorporated herein by reference in its entirety. FIELD OF THE INVENTION [0002] The present invention relates to exercise device for strengthening of abdominal muscles employing resistance mechanism. BACKGROUND OF THE INVENTION [0003] Abdominal muscles support the trunk, allow movement, and hold organs in place by regulating internal abdominal pressure. When these muscles are in poor condition, additional stress is applied to the spine as it supports the body and back injury or pain is more likely. [0004] Exercises for strengthening the abdominal muscles range from simple sit ups and crunches, that requires almost no exercising device, to complex, expensive machines which are strengthening abdominal muscles in seated or laying in supine position. [0005] Effective exercise for the abdominal muscles should strengthen abdominal muscles ...
