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.
An abdominal bench with a fixed seat and a pivoting torso section, comprising:
An exercise bench comprising:
An exercise device having an upper torso supporting portion displaceable relative to a seat portion mounted to a frame, the device comprising a multiple member linkage mechanism pivotally engaging the torso supporting portion to the frame by at least two separated pivot points thereon, the torso supporting portion having a first end proximate the seat portion and a second end remote from the first end, the linkage mechanism being constructed to permit the torso supporting portion to be pivotally displaceable relative to the seat portion through a range of motion wherein each of the first and second ends travel through an arcuate paths having a variable radius of curvature, and to permit a gap defined between the first end of the torso supporting portion and the seat portion to remain substantially constant throughout said range of motion.
An exercise bench including a frame having a seat mounted thereon and a torso portion pivotally engaged to the frame by a linkage mechanism operable such that the torso portion is movable relative to the seat, the linkage mechanism comprising:
An exercise device comprising:
