Abstract: An exercise cycle of the invention includes a frame, a seat, a pedal assembly, an air-resistance device, and a movable handlebar assembly. The crankshaft of the pedal assembly is attached to a first gear which is then in turn mechanically linked to the second gear and pivotally attached to the handlebars to cause an oscillating synchronous motion upon operation of the pedal assembly.

Abstract: A cross country skiing exercise machine has an upright member and an extension member which are structured to move between a first upright configuration and a second configuration in which they are collapsed. The main member is positioned substantially between the parallel tracks of the cross country ski exercise machine. The feet underneath the exercise machine constitute posts about which a reciprocating strap is trained. A rotatably pair of posts are positioned about the strap to tension the strap to cause increased friction and in turn increased resistance to movement of a first trolley and a second trolley which are positioned on the tracks for operation by the user in the performance of cross country type exercises.

Abstract: A control console for exercise machines such as treadmills and stationary cycles having a microprocessor to generate signals to control the exercise and to regulate the heart rate of the user by varying the resistance to the exercise.

Abstract: An exercise cycle having dual resistance structure as disclosed. An exercise cycle utilizing a pedal and crank and sprocket to drive a chain to a front mounted plastic wheel which employs a plurality of blades to form a fan to provide air resistance when the wheel is rotated. Additionally, the hub of the wheel is contacted with a strap to cover a significant portion of the circumference of the wheel whereby the strap may be tightened to increase the frictional resistance between the strap and the hub of the wheel to provide additional resistance when the front wheel is rotated by means of an exerciser pedaling the exercise cycle. A heat dissipation band covers the circumference of the wheel to dissipate heat due to the frictional resistance of the strap.

Abstract: An exercise machine may be positioned in a first configuration in which it may be used for rowing-type exercises and in a second configuration in which it may be used similar to a slant board. A track has a post rotatably positioned between a first position in which it extends upwardly from the track and a second position in which it extends downwardly for contact with the support surface to angulate the track from the support surface. A support cushion may be attached to the track upon which the user resides while performing slant board exercises in the second configuration and for performing other exercises in the first configuration.

Abstract: An exercise cycle of the invention includes a frame, a seat, a pedal assembly, and movable handlebar assembly and an air resistance device mounted at the rear of the cycle. The frame has a rear support unit, a front support unit and an interconnecting member between them. A diagonal member is attached to the rear support unit and angles upward toward the front of the cycle. The seat is attached to the top of this diagonal member. The pivoting handlebars extend upward from the first support unit. An empty space is provided between the diagonal member and the handlebars.

Abstract: An exercise cycle has an upright member with a drive axle and an idler axle each having drive sprockets and idler sprockets interconnected and all positioned within the rim of a flywheel and within the coacting cover which together with the flywheel forms a thin cylinder about the upright member of the exercise cycle.

Abstract: An exercise cycle having a frame, a pedal actuated gear arrangement and an impeller, mechanically associated with that gearing arrangement, is disclosed. The impeller is housed within a chamber defined within a housing mounted on the frame. The chamber includes an inlet opening for introducing a stream of environmental air into the chamber and an outlet opening adapted for directing a flow of pressurized air generated by the impeller's rotation over the body of the user.
