Isometric exercising device

An exercise device comprising,

• a frame connected to a base;
• first and second J-shaped pedal bars mounted at a pivot to said frame said pedal bars having a lower end and an upper end, said lower ends terminating in foot pedals, the foot pedals being movable in substantially back-and-forth type motion,
• a pulley secured to said frame,
• a cord fastened at one end to said first pedal bar and at an opposite end to said second pedal bar, said cord running through said pulley for enabling said back-and-forth motion, and
• a first and second arm, said first arm extending beyond said pivot from said upper end of the first pedal bar, said second arm extending beyond said pivot from said upper end of said second pedal bar, each of said arm terminating in a handle, said back-and-forth type motion pivoting an associated arm in an opposite direction.

An exercise device comprising,

• a frame secured to a base,
• first and second pedal bars pivotally mounted to a upright shaft of said frame and terminating in foot pedals below the pivotal mounting, the foot pedals being movable in a substantially back-and-forth motion, said pedal bars having upper ends and lower ends, said upper ends extending above the pivotal mounting and beyond said shaft into first and second arms, each said arm terminating in a handle,
• a pulley secured by a block to said frame,
• a cord fastened at one end to said first pedal bar and at an opposite end to said second pedal bar, said cord running through said pulley for enabling said back-and-forth motion
• a spring having first and second ends,
• a brake fastened to said first end of said spring, and held in pressed contact with said lower ends of said pedal bars by said spring, and
• spring adjusting means attached to said frame and to said second end of said spring for adjusting tension of said spring, thereby modifying the pressure of said brake against said lower ends of said pedal bars.
