A method for controlling breathing of a user during workout with an exercise machine is provided. The method includes acquiring, by a data processing unit of the exercise machine, at least one parameter representative of a physical exercise being performed by the user with the exercise machine, determining, by the data processing unit of the exercise machine, an indication of the breathing to be followed by the user while performing the physical exercise based on the acquired at least one parameter representative of the physical exercise, and providing the user, by the data processing unit of the exercise machine, with the determined indication of breathing. An exercise machine implementing the method for controlling breathing of the user during workout is also provided.

A double drawcord winding device has a belt pulley supported by a belt pulley bearing to mount on a webbing wheel shaft, two one-way bearings disposed on two sides of the belt pulley bearing, a second shaft sleeve securely mounted on the belt pulley and mounted around the one-way bearings, two winding devices disposed on two sides of the belt pulley and each having a first shaft sleeve extended toward the belt pulley, inserted into and mounted in one of the one-way bearings, each winding device having a winding bearing, a pull cord and a coil spring with two ends, two locating sleeves mounted on the webbing wheel shaft and mounted in the winding devices, one of the two ends of the coil spring connected to the locating sleeve, and other end connected to the winding device.

An exercise equipment device comprises a frame provided with a first end, a second end and two side rails extending from the first end to the second end, a moving carriage supported by the side rails being configured to perform a movement in translation along at least one portion of a length of the side rails and having a planar support surface, a first set of springs supported by the carriage, the first set of springs being configured to extend toward at least the first end of the frame, two transverse crossmembers, and four profiled feet formed by a profile having a closed outer cylindrical peripheral casing and a cylindrical interior channel.

A rower includes a main frame, a second frame pivotally connected to the main frame with one end thereof and having a protruding portion, a handlebar provided with a slot that corresponds to the slot in size and has the configuration complementary to the protruding portion, and a first magnetically attractive member and a second magnetically attractive member respectively and fixedly installed in the slot of the handlebar and the protruding portion of the second frame and magnetically attractable to each other. In this way, in the process of bending the second frame, the handlebar is not easy to detach from the second frame, so the user can fold the handlebar relatively conveniently and easily, and can avoid the handlebar from being damaged by accidental falling during the folding process.

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 rowing exercise device comprises a support structure; a movable user support movably associated with the support structure for movement relative to the support structure; a movable foot support movably associated with the support structure for movement relative to the support structure; a handle; and a rowing assembly operatively associated with the handle and at least the movable foot support to cause at least the movable foot support to move relative to the support structure with movement of the handle so that both a user s body and one or both feet move relative to the support structure with movement of the handle.

The present invention concerns an improved rowing machine, for the execution of gymnastic exercises similar to strokes and the like, comprising actuating means movable between a rest position and a working position, and a first braking device, operatively connected to said actuating means configured to brake the motion of said actuating means during the passage from said rest position to said working position, characterized in that said rowing machine comprises a second braking device operatively connected to said actuating means, said second braking device being configured to brake the motion of said actuating means during the passage from said rest position to said working position.

A rowing simulation trainer includes a base frame, a pulling unit, an inertia wheel unit and a guiding unit. The pulling unit includes a shaft, a first belt wheel, two cord wheels, two pulling cords, two handgrips and two elastic coiled plates. The guiding unit includes two mounting tubes. Each of the two pulling cords extends through one of the two mounting tubes. Thus, the two cord wheels and the two pulling cords cooperate to drive the inertia wheel unit and are respectively operated independently without interfering with each other. In addition, the two pulling cords are limited by the two mounting tubes so that the two pulling cords are kept in line with and will not be deflected from the two cord wheels.

A rowing machine includes a frame where the frame includes a first support, a second support, and a beam extending between the first support and the second support. A track is defined by at least a portion of the beam, and a sliding member is movably disposed on the track. A hinge joint is disposed in the beam between the first support and the second support defining a first section of the beam and a second section of the beam.

An electricity generating system using fitness equipment, wherein the fitness equipment can be used to produce electricity with a generator. The electricity produced can be transferred from the generator to a splitter. A controller can be used to receive identifications and decisions on transfer of the produced electricity from a fitness center. The controller can be used to track in real time electricity produced as watts or as amperage associated with a user identification, a fitness class identification, or an administrator identification input less than 10 minutes before the electricity is produced or at a preset time, which can then transfer in real time energy credits equivalent to electricity produced or transfer produced electricity to a destination designed in the a user decision, a fitness class decision, or an administrator decision.
