Improved exercise assemblies and related methods of use are provided. More particularly, the present disclosure provides advantageous exercise assemblies that are adjustable, changeable and/or rotatable. The present disclosure provides for an exercise assembly that can function as a straight pull-up bar in one arrangement, and can also function as a dynamic, range-of-motion exercise assembly in another arrangement. The exemplary exercise assembly includes an advantageous design that permits users to not only perform straight bar pull-ups, but also allows users to quickly and easily convert the assembly into a two-handled, variable resistance, bicycle-style crank (e.g., a rotating bicycle pull up bar assembly) in which the user rotates two handles of the bar similar to how a cyclist rotates bicycle pedals.

An exercise apparatus has a repositionable crank with a crank drive. The crank drive is housed in a base unit mounted on a platform. Various exercise machines such as a stationary bike, rowing machine, and elliptical machine are selectively mounted to the base unit and engage the crank drive to provide a variety of exercises.

An adjustable rehabilitation and exercise device, including a rotary member having a plurality of elongated and spaced apart elongated open-ended slots defined thereon, each slot including a plurality of enlargements along the length thereof. A mount is selectively and movably positionable on a selected one of the slots of the rotary member to select an angular location of the mount. The mount includes a slide member movably positionable along the selected slot to a selected radial location along the selected slot to select a radial location of the mount relative to the hub of the rotary member. The mount includes a movable pin having an enlarged head. The pin is positionable to selectively engage the enlarged head thereof within the enlargements of the slot so as to lock the position of the mount along the slot. A patient engagement member is connectable to the mount and movable with the mount.

The specification relates to a mobile exerciser. The mobile exerciser can include a mobile exerciser frame; a foot rest assembly attached to the mobile exerciser frame having a working position and a stored position; and a pedal assembly attached to the mobile exerciser frame having a working position and a stored position. The mobile exerciser can be converted from a push mode to a pedal mode by moving the foot rest assembly into a stored position and the pedal assembly into a working position and the mobile exerciser can be converted from a pedal mode to a push mode by moving the foot rest assembly into a working position and the pedal assembly into a stored position.

A human-powered generator includes a frame and a pedal crankset and crankset sprocket rotatably mounted on the frame, a flywheel rotatably mounted on the frame including a flywheel-crankset sprocket a flywheel-countershaft sprocket, a countershaft rotatably mounted on the frame including a countershaft-flywheel sprocket and a countershaft-alternator sprocket, and an alternator including an alternator drive shaft and an alternator sprocket. The human-powered generator also includes a crankset-flywheel drive chain, a flywheel-countershaft drive chain, and a countershaft-alternator drive chain. A pedaling cadence at the pedal crankset of between approximately 60 RPM and approximately 100 RPM achieves an alternator drive shaft RPM of between approximately 2,000 RPM and approximately 5,000 RPM.

A power measurement assembly mounted within an axle. In a specific example, the axle is a spindle that is interconnects the cranks of a bicycle, exercise, bicycle, or other fitness equipment. The power measurement assembly may include strain gauges connected with an appropriate circuit (e.g., Wheatstone bridge) that provides an output of the force on the axle by a rider pedaling the crank. In the case of an axle, the strain gauges measure the torsion due to the applied torque on the crank. The value is converted to a power value by a processor and that value is then wirelessly transmitted for display. The processor and/or the transmitter may be mounted within the axle. A separate power measurement assembly may be mounted on one of the cranks, which may include its own processor and transmitter or may take advantage of the processor and transmitter within the axle.

The invention provides an exercise machine of the type which have pedals or foot plates through which a person can, in use, transfer kinetic energy to the machine, which machine comprises a means for vibrating the pedals or foot plates during exercise.

An exercise machine may include a frame. The frame may include a base portion, an upright portion coupled to the base portion, and a pivot joint connecting the upright portion to the base portion. The pivot joint may include a drop-in axle connected to the upright portion and a drop-in receptacle connected to the base portion. The drop-in axle may be removably received in the drop-in receptacle.

A power measurement device, which may be mounted to an inside area of a crank arm, includes processing circuitry within a housing. The processing circuitry is coupled with strain gauges mounted on the crank arm, and produces a power value that is wireless transmitted to a separate display that may receive and display power measurements. The housing may include a mounted portion and a cantilever portion where the mounted portion houses the processing circuitry and the cantilever portion houses batteries supply energy for the processing circuitry and other features.

An exercise apparatus with oscillating tilt system includes a main frame for supporting all the components of the apparatus, a tiltable upstanding support is tilted oscillating, a mechanism which enabling a user of the apparatus to move hands and feet up and down harmoniously, and another mechanism to change an orientation of the user in relation to the vertical line oscillating during the exercise, and consequently changing the direction of the forces affecting different muscles of the user of the apparatus.
