Claims16
An exercise bench apparatus for strengthening the muscles of the lower back by confining a portion of the user's body in a relatively immobile position, while permitting the user to freely move between an upright seated position and a forwardly leaning position, comprising:
- a) a beam fixedly mounted at a position which is inclined at substantially 30.degree. relative to the horizontal;
- b) a seat member affixed to said beam;
- c) a knee brace mounted to said beam and at a position spaced away from said seat and proximate a lower end of said beam;
- d) a first restraining means for immobilizing the upper portion of a user's legs relative to said seat;
- said first restraining means comprising a first elongate adjustable belt affixed proximate said seat member whereby said belt may be adjustably tightened about the user's upper leg portions;
- and
- e) a second restraining means for restraining the user's body from movement away from said knee brace;
- said second restraining means comprising a second elongate adjustable belt affixed proximate said knee brace, whereby said belt may be adjustably tightened about the user's lower back portion and whereby the user's knees are held against said knee brace and pelvic rotation about the hip sockets is restrained.
An exercise bench apparatus for strengthening the muscles of the lower back, comprising:
- a) A support member having an upper end adapted for mounting to and affixing an elongate beam at an inclined position relative to the horizontal;
- b) said elongate beam having a first end affixed to said support member upper end, and having a second end downwardly inclined therefrom;
- c) a seat member affixed to said elongate beam proximate said first end;
- d) a knee brace affixed to said elongate beam proximate said second end;
- e) a first adjustable restraint means positionable along said inclined beam proximate said seat member;
- whereby the upper leg may be confined against said seat member;
- and
- f) a second adjustable restraint means positionable along said inclined beam proximate said knee brace and adjustably extensible upwardly toward said seat member;
- whereby the lower back may be restrained from movement away from said knee brace and pelvic rotation about the hip sockets is restrained.
