A footrest assembly is connected to the mast. A recumbent exerciser can not only exercise the main and lower abdominal muscles by pushing and pulling the mast against the resistance of the hydraulic cylinders in a back and forth direction aligned with the longitudinal axis of the bench, but also the side or oblique muscles by simultaneously pivoting the mast back and forth in a transverse direction. The machine also allows a combination of the above motions including a circular type motion in either direction, clockwise or counterclockwise.

Abstract: An exercise machine designed to exercise the upper body, focusing particularly on the core abdominal muscles but also on the arms, shoulders and chest. The machine comprises a structural frame with an adjustable seating mechanism, a handlebar and one or more position-adjustable targets against which a user throws a weighted ball. The machine provides two modes of exercise. In the seated mode the user exercises the abdominal muscles by rocking the body while seated in the flexible, adjustable-resistance, back-supported seating mechanism. The back support element of the seating mechanism is adjustable into a flat position, effectively converting the seat into a bench. In bench mode, the user, laying face up on the bench and holding onto the handlebar for stability, exercises the lower abs by performing leg-raising crunches. The machine is designed to be uniquely stimulating and fun to use. It may be folded compactly for storage.

Abstract: A combined abdominals (main and lower abs)/thighs/calves exercise device, which composes a base support member assembly upon which the user sits, a partially vertical and horizontal resistance mast with resilient restorative properties mounted upon the base support member support, and a collar oriented upon the upper mast. A bracket means is reciprocally mounted upon the collar and is adapted to hold a range of vertical positions along same. A pair of grippable bars transversely mounted upon the outer end of bracket means, which bars permit the user to train and strengthen major and minor muscle sets dependent upon the physical orientation of the grippable bars.

Abstract: A portable exercise device identified for abs and hips conditioning comprising a generally rectangular, rigid frame supporting a tilted seat and laterally aligned, handle bars used for hand bracing when the user is seated thereon. A single lever arm of an elbow configuration is transversely disposed above the seat and is adapted for pivotal lifting which is effected by the thigh movements. The device has a moment means positioned beneath the seat, which means is operatively tied to the lever arm pivot point. Resilient tensioning means are also secured to the frame and provide the variable countervailing force needed to resist the user imposed arcuate movement of the lever arm.

Abstract: A dual-purpose exercise machine, adapted to alternately condition two different sets of muscles, one device mode being for the legs and buttocks muscle sets (the foot stepper mode), and the other device position being for the pectoral/chest muscles and the upper arm muscles (biceps/triceps) in the bench press and ring extension modes. In the stepper mode, the device resembles a conventional stepping machine, having an upstanding vertical mast, conveniently formed by parallel elongate rigid members, set with a transverse span. A planar platform is securely mounted within the frame of the mast. An opposing pair of manual exertion resistance means, conveniently of hydraulic dampers, are disposed substantially horizontal, linked to the lever arms. They are mechanically linked to provide the variable resistance in opposition to alternating depression by user exerted upon foot-step platforms.

Abstract: A lap-based exercise device for conditioning abdominals and arms is provided. It includes a horizontal first pair of parallel members, which pair defines an elongate trough that concurrently receives one end of a rigid spanner bar and a linked one end of an associated band tensioning means. The other end of the spanner bar is pinned to a second pair of upstanding, spaced apart members pressing the torso, with such upstanding members being linked at their lower ends to the longitudinal ends of the first pair via a second torso-side crossbar. A third crossbar is pinned to the outer longitudinal ends of the first parallel pair and includes a pair of manually grippable means for activation of the device. Upon curling movement of the grippable means toward the user torso, the spanner bar and the operatively linked tensioning means provide the counter resistance which allows for a smoother range of arcuate arm motion for the exerciser.
