Abstract: The present invention is an exercise machine providing elliptical strides in substantially lateral directions. The elliptical motion of the pedals is basically a combination of a looped motion of a loop motion means and a reciprocating motion set by a motion guide means following a predefined path. The loop motion means connects the motion of a left pedal to the motion of a right pedal so that the movement of both pedals is dependent. Substantially lateral motions of the left pedal and the right pedal follow lateral predefined paths set by a left motion guide means and a right motion guide means.

Abstract: The present invention is an exercise machine to be used mainly for lower body exercises that involve quads, shins, thighs, and hip areas of a user and provides a moving seat frame that supports the weight of the user to use it as a source of a resistance as a pedal is pushed away. The resistance can be adjusted by changing the ratio between the seat movement and the pedal movement. The machine can be foldable for a stowed position. A preferred embodiment includes a base assembly that stands on a floor, a seat assembly movable substantially in vertical direction to support the user's weight and use it as a source of the resistance, and a pedal assembly supporting a pedal that moves away from the seat assembly when pushed by the user. The pedal assembly and the seat assembly are linked together so that when the pedal is pushed away, the seat assembly is lifted up from its rest position.

Abstract: A lateral motion exercising apparatus provides a pair of vertically oriented axles engaged with a frame. A pair of support struts are rotationally engaged with the axles. A rigid link is pivotally joined at its terminal ends with the support struts in a manner for maintaining the support struts in parallel alignment as they rotate about the axles. A pair of platform struts is engaged pivotally at proximal ends of the support struts, the pivots enabling each of the platform struts to rotate vertically about its distal end. The proximal ends of the platform struts are constrained to move in opposing vertical motions in coordination with rotations of the support struts to produce a skating-like motion to a user standing on the platform struts.

Abstract: A foldable treadmill is provided that can be easily reoriented for variable exercise inclinations, as well as, for convenient storage. The treadmill includes a tread assembly and an A-frame assembly positioned about the front end of the tread assembly. The A-frame assembly includes an inclination support connected to a front end of the tread assembly by hinges for varying inclination of the tread assembly. The inclination support can be driven by a motor to rotate the inclination support about such that the inclination support vertically displaces the front end of the tread assembly thereby varying the inclination of the tread assembly. The A-frame assembly includes intermediate and front supports hinged to each other at upper ends thereof. The tread assembly is rotatable to a generally vertical orientation for storage. In the stored position, the spacing between front and intermediate supports is reduced, further facilitating storage.

Abstract: An improved press arm allows an operator to perform either a traditional straight chest press exercise or to incorporate “butterfly” motion during the performance of the chest press exercise. A main arm is pivotally coupled to the frame of the exercise machine at a main pivot in the same manner as conventional press arms. The main arm includes a cross-beam to which a pair of handle arms are pivotally coupled at secondary pivots. The axes of the secondary pivots are orthogonal to the axis of the main pivot and are inclined with respect to vertical when the press arm is in a rest position. This inclination causes the handle arms to assume a natural rest position under the influence of gravity. The rest positions of the handle arms place the press arm handles at a comfortable starting position for performance of a press exercise. Stops to limit the inward or outward travel of the handle arms are not necessary.

Abstract: A pair of a skater foot supports are joined with a skating motion director including, a simple crank interconnected with the foot supports by a pivotal linkage, such that as the crank rotates in a circle, one of the foot supports is pulled and the other pushed during a first one-half of the circle rotation, while, the reverse occurs during the second one-half of the circle rotation. The crank is rotationally engaged with a flywheel through a mechanical drive train, enabling the flywheel to rotate at a speed greater than that of the crank whereby the foot supports move with a skating motion for exercising a skater.
