Provided is a virtual road surface implementation-type bicycle simulator. The virtual road surface implementation-type bicycle simulator according to the present disclosure includes a rear wheel support portion that supports a rear wheel of a mounted bicycle and rotates together with rotation of the rear wheel; and a road surface implementation portion including a plurality of uneven portions that perform a protrusion operation at various heights on an outer peripheral surface of the rear wheel support portion in contact with the rear wheel, thereby providing a rider riding the bicycle with various road surface states which are virtually set.

A reciprocating transmission structure of an exercise machine, mounted to a frame of the exercise machine, includes a first reciprocating member, a second reciprocating member, a main rotating wheel, a first link, a second link, and a resistance wheel. The first reciprocating member reciprocally moves with a first reciprocating pivot portion as its axis. The second reciprocating member reciprocally moves with a second reciprocating pivot portion as its axis. The first link and the second link drive the main rotating wheel to rotate with a rotating shaft as its axis. The main rotating wheel drives the resistance wheel to rotate. After the first reciprocating member and the second reciprocating member move reciprocally, the resistance wheel can be driven to rotate by the cooperation of various components. The exercise machine is suitable for performing exercises related to reciprocating movement, and the operation is easier.

An exercise device is provided, including: a main body, two fan wheels and a magnetic resistance assembly. The main body includes an axle disposed thereon. The two fan wheels are connected to the axle and rotatable relative to the main body. The magnetic resistance assembly includes two magnetoresistive rings disposed respectively on the two fan wheels and around the axle, a magnetic unit and a controlling unit. The magnetic unit includes two magnetic portions respectively corresponding to the two magnetoresistive rings. The controlling unit includes a lever rotatably disposed on the main body at a pivot point, and the magnetic unit and an operating portion are disposed on the lever and located by two opposite sides with respect to the pivot point. The pivot point and the axle are eccentrically arranged.

A training apparatus for the simulation of rowing training includes a rolling seat to be moved linearly back and forth on a guide on a frame. Two handles which can be rotated independently of one another are mounted on an oarlock shaft. The oarlock shafts are connected to a drive mechanism in a force-flow connection. Upon introduction of force to the handles, power is output to a braking device via a drive mechanism, which has a freewheel between the oarlock shafts and the braking device. Upon actuation of the handles in a first direction about the axis of the respective rowlock shafts, power is transmitted to the braking device, and, upon actuation of the handles in the opposite direction the handles return without power being transmitted to the braking device.

A rowing machine is disclosed. The rowing machine includes a frame including a base for contact with a support surface and a seat rail supported by the base. The rowing machine includes a seat configured to reciprocate back and forth along the seat rail. The rowing machine includes a rowing engine that includes at least one resistance mechanism rotatably coupled to the frame. The rowing machine includes at least one handle operatively connected to the at least one resistance mechanism, and a paddle linkage assembly operatively connecting the at least one handle to the at least one resistance mechanism such that rearward movement of the handle is resisted by the at least one resistance mechanism.

A flywheel exerciser having a hybrid resistance system includes: a body having a flywheel unit; a wind resistance system disposed on the flywheel unit; and a magnetic resistance system disposed on the flywheel unit. The wind resistance system is a conventional wind resistance which provides segmental adjustment, the present invention is additionally provided with a magnetic resistance system. When the resistance generated by the wind resistance system is insufficient or excessive, the resistance can be further finely increased or decreased by adjusting the magnetic resistance system to provide the resistance that best meets the user's needs.

Aspects herein provide for an apparel item having an integrated parachute structure and a set of intake ducts. The parachute structure is configured to transition from a first slack state to a second inflated state subsequent to air entering the set of intake ducts incident to ground locomotion of the wearer thereby increasing air resistance to wearer movement.

A portable exercise device provided includes: a base disc, two pulley assemblies, a support plate, and a fan wheel assembly. A support plate is disposed on the base disc, the two pulley assemblies are provided on the base disc, and the fan wheel assembly is provided on the support plate, so that the fan wheel assembly and the two pulley assemblies are vertically arranged on top of each other, thereby reducing the overall volume. More preferably, because the volume is reduced, the user can arbitrarily move and hang the portable exercise device at the desired position, and because the portable exercise device of the invention can be hung at different positions, which allows the user to train different muscles according to the different positions.

An exercise machine allows a user to perform a variety of resistance exercises with adjustable resistance levels. The machine is made up of an arm, a user platform, a horizontal base, an adjustable counterweight arrangement, a pull rod, a drive chain system, sprockets, shafts, adjustable fan, a slip bearing, a recoiler, a plurality of wheels, a drive chain system housing, a user back support, a user cable grip, and a circuit-breaking sensitive rubber mat. When the arm is moved upwards (by a user) the pull rod attached to a drive chain initiates the drive chain system rotation. The drive chain system rotation includes an adjustable weight fan that creates resistance to the arm's upper movement through inertia. The adjustable counterweight arrangement determines the arm drop speed and the arrangement has multiple positions. Other variants include a plurality of electronic encoders.

The present invention relates to a boxing fitness device and a detection method thereof, the boxing fitness device of the present invention includes a frame, punching zones, prompting devices, sensing devices, a first wearable device, a second wearable device and a computation unit. The punching zones are disposed in the frame and the prompting devices are disposed on the punching zones, respectively. When a left hand or a right hand of a user touches one of the punching zones, the sensing devices can sense a first to-be-sensed part of a first wearable device or a second to-be-sensed part of a second wearable device worn on the hands of the user. As a result, the boxing fitness device and the detection method thereof of the present invention can sense the first to-be-sensed part and the second to-be-sensed part to detect the user's correct punching action.
