A collapsible cycling exerciser is an apparatus that effectively exercises a user through full ranges of motion and varied resistance. The apparatus includes a first support post, a second support post, a left handlebar, a right handlebar, a left pedaling mechanism, a right pedaling mechanism, and a torsional resistance mechanism. The first support post and the second support post, together, upholds and positions the user. The left handlebar and the right handlebar guide the linear movement of the arms. The left pedaling mechanism and the right pedaling mechanism guide the rotary movement of the legs. The torsional resistance mechanism applies resistance to the left handlebar, the right handlebar, the left pedaling mechanism, and the right pedaling mechanism. In the preferred embodiment of the apparatus, a hinged connection secures the first support post and the second support post to each other so that the apparatus is collapsible.

An exercise apparatus comprising: a foot support, a user interface that includes a visual display, the foot support being movable by the user on the frame back and forth through any one of a plurality of complete, reproducible and different arc segments of a master arcuate path, the foot support being interconnected to a selection device that enables the user to select any one of the plurality of arc segments, one or more detectors adapted to detect one or more of force, energy or power exerted by the user over time on the foot support or distance or velocity of travel of the foot support or resistance assembly during the course of the user's performance of all or a portion of an exercise cycle, the visual display displaying a visually recognizable format of one or more of the force, energy, power, distance, time or velocity.

An exercise machine includes a frame and a resistance mechanism attached to the frame. A crank assembly in mechanical communication with the resistance mechanism, and the crank assembly includes a crank arm and a roller connected to the crank arm. A pedal assembly is movably attached to the crank assembly and movable in a performance of an exercise. The pedal assembly includes a pedal beam and a first tensioned element that spans at least a first portion of an underside of the pedal beam. A second tensioned element spans a second portion of the underside of the pedal beam and the roller is disposed between the first tensioned element and the second tensioned element.

A pedal exercise signal detection device includes a sleeve having an outer circumference having a pressure signal connection device and a pressure detection unit mounted thereon; a first bearing disposed in the sleeve; a stator having a positioning axle having an end formed with a fastening hole; a fastener element fastening the stator and the sleeve together; a pedal having an axle hole into which the sleeve is inserted to be positioned therein and a receiving trough including a through opening corresponding to the pressure signal connection device; and a control circuit board disposed in the receiving trough and including signal reader units that extend through the through opening and corresponding to the pressure signal connection device.

The improved stationary bicycle is a self powered exercise bicycle that may, in addition to building strength with the type of resistance exercise that is typically done with standard exercise bicycles, may be used to move the muscles of an individual that is too feeble to rotate the pedals on their own through a full range of motion using the self powered function. A brake lever on one of the handles of the handle bars may be used to stop the pedals from rotating. A programming function allows the user to select various user preferred speeds.

An air-cleaning fitness device has a main frame, a housing, a driving assembly, a fan device and at least one filter. The housing, the driving assembly and the fan device are mounted on the main frame. The housing has a confined space and an airflow passage. The driving assembly and the fan device are located inside the housing and connect to each other. The fan device has a second inlet and a second outlet. The second inlet and the second outlet are respectively aligned with two ends of the airflow passage. The at least one filter is mounted on the housing and is capable of covering either end of the airflow passage. The driving assembly has at least one driving member which extends out of the housing and drives the fan device. When the user operates the air-cleaning fitness device, the air-cleaning fitness device purifies the air at the same time.

A control device for an electrical stimulation apparatus according to the present disclosure includes a control section that adjusts an output of an electrode and communicates with an angular velocity detector, the electrode giving electrical stimulation to a predetermined part of a body doing a pedaling exercise by rotating a crank, the predetermined part being at least one of a leg and an arm, the angular velocity detector detecting an angular velocity of the predetermined part, the angular velocity being accompanied by an operation of the predetermined part during the pedaling exercise. The control section adjusts, according to a result of the detection in the angular velocity detector, an output timing of the electrical stimulation of the electrode such that the electrode gives electrical stimulation to the predetermined part when a state of the operation of the predetermined part during the pedaling exercise is a predetermined operation state.

A control device for an electrical stimulation apparatus in the present disclosure includes a control section that adjusts an output of an electrode. The electrode gives electrical stimulation to a predetermined part of a body doing a pedaling exercise. The predetermined part is at least one of a leg and an arm. The control section adjusts the output of the electrode in such a way that the electrical stimulation is given to the predetermined part in relation to an exercise unit of the pedaling exercise. Furthermore, the control section adjusts strength of the electrical stimulation related to the exercise unit, in accordance with an amount of a physical activity of the body during the pedaling exercise. In this way, electrical stimulation can be given to a predetermined part in a variable manner during the pedaling exercise.

Provided is a control apparatus for an exercise therapy device to be used to carry out interval training where a high-intensity exercise and a low-intensity exercise, which have different exercise loads, are alternately carried out, including: an exercise load setting part for inputting an exercise load and exercise time period for the high-intensity exercise and low-intensity exercise from an input device of the exercise therapy device and setting the input exercise load and exercise time period in a storage part of the exercise therapy device as an exercise program; and a display control part for displaying a timing at which an exercise intensity of the exercise program is to change next during the interval training on a display device of the exercise therapy device.

An exercise apparatus comprising: a foot support, a user interface that includes a visual display, the foot support being movable by the user on the frame back and forth through any one of a plurality of complete, reproducible and different arc segments of a master arcuate path, the foot support being interconnected to a selection device that enables the user to select any one of the plurality of arc segments, one or more detectors adapted to detect one or more of force, energy or power exerted by the user over time on the foot support or distance or velocity of travel of the foot support or resistance assembly during the course of the user's performance of all or a portion of an exercise cycle, the visual display displaying a visually recognizable format of one or more of the force, energy, power, distance, time or velocity.
