ABSTRACT:
An exercising machine and method is disclosed wherein a rigid body supporting platform is supported at one end at a level such that the supporting surface is inclined at an angle to the horizontal. The support is constituted by a U-shaped tubular frame member and a standard portion which is secured to the U-shaped frame member. The rigid body supporting platform has a notch at one end thereof through which the standard passes and means are provided for rotatably mounting the U-shaped frame member on the underside of the supporting platform. A pair of crank and pedal means are rotatably mounted such that a downward weight on the underside of the platform by the weight of the user urges the standard towards the user and the legs of the U-shaped member away from the weight to thereby stabilize the platform. A flexible non-extensible strap has a handle at one end and is adjustably connected to the standard so that the tendency of the user to slide downwardly due to gravity and due to exertion of pedaling on the pedals is opposed by the user exerting a force on the standard in a direction urged by the weight and to urge the user's body up the incline surfaces. Thus, both the upper torso of the user is isometrically exercised at the same time that the lower torso and legs are being exercised by pedaling activity.
