An exercise device in the nature of an exercise bicycle includes a ground supported frame, a seat supported by the frame, a first flywheel supported for rotation by the frame, and pedals operatively connected to the first flywheel such that rotation of the pedals causes rotation of the first flywheel. A user positioned on the seat and turning the pedals with his feet may obtain aerobic exercise for the lower portion of the body. Additionally, a second flywheel is supported for rotation by the frame, and handlebars are operatively connected to the second flywheel such that alternately pushing and pulling on the handlebars causes rotation of the second flywheel. The handlebars may be moved by the user to turn the second flywheel to obtain aerobic exercise for the upper portion of the body independently of, or simultaneously with, the aerobic exercise of the lower portion of the body. Each of the flywheels is provided with an adjustable friction band by which resistance to the respective flywheel may be controlled by the user. Further, each flywheel is provided with a free-wheel clutch which permits the handlebars and the pedals to be brought to an immediate stop as desired by the user, without the user being required to overcome the inertial force of the respective flywheel.

A dual action exercise device, comprising: a ground supported frame having a seat, wherein the seat includes a lower-back support, and wherein the frame includes a rearwardly disposed, upwardly extending tubular member which telescopingly receives a seat supporting member therein for positioning the seat; means for adjustably locking the seat supporting member within the upwardly extending tubular member in a manner permitting selective height adjustment of the seat, the locking means including a spring-loaded pin supported by the upwardly extending tubular member and extending therethrough for engagement with one of a plurality of apertures provided in the seat supporting member; pedal means supported by the frame and including a first crank, a first crank shaft, a first bearing housing supported by the frame and surrounding the first crank shaft, and a first drive sprocket carried by the first crank shaft; first flywheel means supported for rotation by the frame and operatively connected to the pedal means such that rotation of the pedal means causes rotation of the first flywheel means, the first flywheel means including a first flywheel and a first driven sprocket which is coplanar with the first drive sprocket and connected thereto by a silent chain whereby rotation of the first drive sprocket causes rotation of the first driven sprocket, which, in turn, causes rotation of the first flywheel, wherein the first flywheel means further includes a first free-wheel clutch connecting the first flywheel to the first driven sprocket, whereby the first free-wheel clutch permits motion to be transmitted from the first driven sprocket to the first flywheel in one direction only; first friction band means anchored to the frame and engaging at least a portion of the first flywheel means to provided controlled resistance to rotation of the first flywheel means, wherein the first friction band means includes a first band brake extending around at least a portion of the periphery of the first flywheel, and means for adjusting the tension of the first band brake about the first flywheel, whereby one end of the first band brake is anchored to the frame, and another end of the first band brake is adjustably positioned with respect to the frame by the first band brake adjusting means to provide selectively adjustable resistance to the first flywheel means; handlebar means including a handlebar pivotally supported by the frame, a second crank shaft, a second bearing housing supported by the frame and surrounding the second crank shaft, a second drive sprocket carried by the second crank shaft, and means for connecting the handlebar to the second crank shaft such that alternately pushing and pulling on the handlebar causes rotation of the second crank shaft, wherein the means for connecting the handlebar to the second crank shaft includes a link connected at a first end to the second crank shaft, and a connecting bar pivotally attached to a second end of the link at one end, and pivotally attached to the handlebar at another end; second flywheel means supported for rotation by the frame and operatively connected to the handlebar means such that alternately pushing and pulling on the handlebar means causes rotation of the second flywheel means, wherein the second flywheel means includes a second flywheel and a second driven sprocket which is coplanar with the second drive sprocket and connected thereto by a silent chain whereby rotation of the second drive sprocket causes rotation of the second driven sprocket, which in turn causes rotation of the second flywheel, wherein the second flywheel means includes a second free-wheel clutch connecting the second flywheel to the second driven sprocket, whereby the second free-wheel clutch permits motion to be transmitted from the second driven sprocket to the second flywheel in one direction only; and a second friction band means anchored to the frame and engaging at least a portion of the second flywheel means to provided controlled resistance to rotation of the second flywheel means, wherein the second friction band means includes a second band brake extending around at least a portion of the periphery of the second flywheel, and means for adjusting the tension of the second band brake about the second flywheel, whereby one end of the second band brake is anchored to the frame, and another end of the second band brake is adjustably positioned with respect to the frame by the second band brake adjusting means to provide selectively adjustable resistance to the second flywheel means; whereby lower body exercise can be achieved by foot activating the pedal means while upper body exercise can be achieved, either simultaneously or independently, by pushing and pulling the handlebar means.
