A unique abdominal bench with a pivoting torso section has a number of pivots, rods, and levers that allow the fixed seat section of the abdominal bench to remain a constant distance from the pivoting torso section during an abdominal exercise. The leg section of the abdominal bench pivots towards the abdomen, as does the torso section when the torso is raised. The leg section is pivotably connected to the torso section through a number of rods, pivots and levers such that the gap between the seat and torso section remains the same. A push rod is connected to the pivoting leg brace and is in turn connected to a torso bracket through several guide rods and a dog-leg lever. The push rod, guide rods and the dog-leg lever allow the torso section to remain a constant distance from the fixed seat section. Allowing the torso and seat section to remain a constant distance eliminates the pressure on the lower body of the exerciser and will not cause any movement of the lower body of the exerciser with respect to the torso section.

L'invention concerne un banc abdominal unique pourvu d'une section torse pivotante. Ce banc a un certain nombre de pivots, barres et leviers qui permettent à la section siège fixe du banc abdominal de demeurer à une distance constante de la section torse pivotante pendant un exercice abdominal. La section jambe du banc abdominal pivote vers l'abdomen, comme le fait la section torse lorsque le torse se soulève. La section jambe est articulée rotative à la section torse par un certain nombre de barres, pivots et leviers de telle manière que l'écartement entre la section siège et la section torse demeure identique. Une barre-poussoir est connectée à l'attelle jambière pivotante et est, à son tour, connectée à un support de l'attelle torse par plusieurs barres de guidage et un levier coudé. La barre poussoir, les barres de guidage et le levier coudé permettent à la section torse de rester à une distance constante de la section siège fixe. En permettant à la section torse et à la section siège de rester à une distance constante, on élimine la pression sur le bas du corps de l'exerciseur et cela n'engendre pas de mouvement du bas corps de l'exerciseur par rapport à la section de torse.
