Abstract: The present invention provides a treadmill for allowing an exerciser to perform walking or running exercise on an endless belt. The treadmill is selected to be operated in a forward movement mode or in a reverse movement mode. In the reverse movement mode, a control unit of the treadmill controls a driving device to drive a top surface of the endless belt to slide forward for allowing the exerciser to simulate backward walking. When a detecting device detects that the exerciser enters a warning area in front of a normal range of movement, a reaction mechanism would be triggered to control the driving device to slow down or stop the endless belt. In the forward movement mode, the control unit controls the driving device to drive the top surface of the endless belt to slide backward and to disable the reaction mechanism.

Abstract: An exercise apparatus includes a frame adapted to be rested on a floor surface, a crank mechanism that has two cranks mounted on the frame, two swing members pivotally mounted on the frame, two connecting assemblies, and a guiding device. Each of the two connecting assemblies has a plurality of connecting rods connecting the respective crank and the respective swing member. The two connecting assemblies define two pedal portions for supporting a user's feet, and up-and-down movement of the pedal portions causes rotation of the two cranks along a circular path. The guiding device is configured to connect the two swing members for guiding swing movement of the two swing members within a predetermined swing range. The predetermined swing range is adjustable so as to provide various exercise paths.

Abstract: The present invention provides an exercise apparatus for allowing a user to perform an exercise. The user drives at least one moving member to rotate a flywheel. The flywheel must overcome a resistance generated by a magnetic field generating module during rotation. In a preferred embodiment, the magnetic field generating module is supported by a flexible support member and tends to restore to an initial position. The magnetic field generating module will be pushed by the flywheel in a rotational direction of the flywheel and to generate a corresponding displacement. The displacement or the deformation of the support member is measured by a first measuring device so as to appropriately calculate the output force of the user, and further obtains power, metabolic equivalent or calorie consumption rate if correlated with rotational speed of the flywheel or corresponding parameters measuring by a second measuring device.

Abstract: An exercise apparatus includes a motion mechanism and a handle assembly. The motion mechanism is provided for a user to perform exercise. The handle assembly has at least one grip portion for being held by the user during exercising. Specifically, the grip portion has a temperature variable area thereon. The temperature of the temperature variable area could be controlled to rise to a suitable temperature that the hand of the user can feel warm, for example, a temperature between 38 and 50 degrees Celsius. The temperature of the temperature variable area could also be controlled to reduce to a suitable temperature that the hand of the user can feel cool, for example, a temperature between 20 and 36 degrees Celsius. The temperature of the temperature variable area could be directly controlled by the user or automatically changed according to the exercise status of the user.

Abstract: An exercise apparatus includes a resistance system which has a first rotating shaft, a second rotating shaft and a transmission mechanism mounted between the two rotating shafts, such that the two rotating shafts are rotated with respect to each other at a predetermined transmission ratio. Besides, a first resistance device is controlled to apply a first resistance against rotation of the first rotating shaft, and a second resistance device is controlled to apply a second resistance against rotation of the second rotating shaft. The first resistance device and the second resistance device can be controlled independently. When a user uses the exercise apparatus to perform exercise, a moving member is driven by movement of the user. When the moving member is moved, the two rotating shafts are driven to rotate simultaneously, namely the user has to overcome the rotational resistance of the two rotating shaft during exercise.

Abstract: The present invention relates to an exercise apparatus. The exercise apparatus includes a platform which has an endless belt revolved around it. The endless belt defines an exercising space. A left strap extends from a left front portion to a left rear portion of the exercising space, and a right strap extends from a right front portion to a right rear portion of the exercising space. The left strap and the right strap respectively have a first connecting part and a second connecting part which could be connected or detached with each other. When the two connecting parts are connected with each other, the left strap and the right strap form a retaining portion for resisting forward movement of a user. When the two connecting parts are detached, the left strap and the right strap could be positioned on a left side and a right side of the exercising space.
