The present invention is a horizontal rowing machine having a frame with a removable seat, adjustably mounted on the frame and an adjustable chest pad. The present invention has angled foot plates. The foot plates enable the user to use the machine in various positions. The present invention has two fixed multi-grip handles with 8 fixed hand positions and 6 positions on which to attach swivel handles. The swivel handles allow for a more natural and free form rowing movement. Maximal adjustability of all aspects of the machine allow for a more optimal and beneficial training exercise for any user, regardless of body size. The user can lift a desired weight by pulling the handles.

The invention (variants) relates to a field of sports and medicine, and it concerns training devices, namely, rotary training machines which are used for a simultaneous training of human should, pelvic girdles, and trunk muscles. The claimed invention is based on a task to create a rotary multi-function training machine for the simultaneous training of human shoulder girdle, pelvic girdle, and trunk muscles, while involving all groups of muscles in a balanced manner in order to provide a high quality and efficiency of the trainings at different usage modes of the training machine due to maintaining a synchronization of a rotation of shafts of load modules of the training machine by adjusting a relationship between their rotational speed and efforts applied thereto.

An exercise device featuring a pair of knee joints, each pivotally coupled to a pair of calf linkages having foot pedals at their opposite lower end that support low impact user-defined natural exercise gait patterns. The knee pivots joints are supported and directed to travel by linkage and/or carriage systems that operate substantially below the user hip area, and direct the knee pivot joints in a variety of travel paths, ranging from having a constant arc, linear pathway, to having a variety of irregular arc shaped paths, as well as, pathways that may change during use. A secondary system coupled to the knee pivot support system, provides lift and dampening forces to influence the responsiveness of the foot pedals via the bending and straightening of the calf linkage about the knee pivot joint, yet do not restrict the back and forth travel of the knee joint.

The present invention relates to an adjustment device for exercise apparatuses, which comprises a flange (4), a coupling body (6) coupled to said flange (4) by means of a pressure bar (61d), adjustment protrusion (6e) and pressure pin (6g), a coupling ring (5) through which the coupling body (6) is passed, a vertical arm (8) connected to said coupling body (6) so as to be adjusted in the back and forth direction and rotationally, and a coupling arm (9) connected to said vertical arm (8).

A fitness apparatus and a method for assembly are disclosed. The fitness apparatus comprises a wheel assembly that includes a first circular side parallel to a second circular side, both bounded by a curved tread. Within the wheel assembly is an enclosable storage chamber. The fitness apparatus also includes an axis perpendicular to the first circular side and the second circular side, and when the fitness apparatus is in an abdominal exercise wheel configuration, at least a portion of the wheel assembly rotates around the axis. The fitness apparatus also includes a centerbore along the axis that supports a first removable handle and a second removable handle when the fitness apparatus is in the abdominal exercise wheel configuration.

Lever-type rowing machine, whose main rigging dimensions meet the corresponding parameters of sweep rowing or sculling boat is mounted to the base frame by using front and rear elastic suspension so that the simulator makes it possible to rotate (tilt) about its transverse and longitudinal axes and move vertically, thus making it possible to simulate the boat swings on the transverse and longitudinal axes and movement in the vertical direction. In addition, the simulator has passive and active stabilization systems, enabling the athlete to maintain a balance, and stiffness of its front and rear suspension and stabilizer system can be adjusted depending on the weight and balancing ability of user. There is also a possibility to constraint the suspension thus ensuring full stability of the simulator and exercise regime, corresponding to the exercising on common rowing machines.

An elliptical trainer comprises a frame set, two first transmission rods, two second transmission rods, two footboard assemblies, a holding flywheel assembly, a stand flywheel assembly, and two eccentric link rods. When a user is stepping the two footboard assemblies and taking exercise with elbows on the two second transmission rods, the two footboard assemblies may be stepped up and down to recycle and each second transmission rod may be rotated to reciprocate along an arc and centered in a stand ear. At this time, each drag rod of two stand ears arranged right and left may pull the corresponding eccentric link assembly to rotate 360 degree and the torque of the third flywheel may not overlap each drag rod of each eccentric link assembly vertically. Accordingly, the arrangement of each eccentric link assembly may prevent the swing operation from being stuck to pause or operate unsmoothly.

A method is disclosed for using an artificial intelligence engine to perform a control action. The control action is based on one or more measurements from a wearable device. The method includes generating, by the artificial intelligence engine, a machine learning model trained to receive the one or more measurements as input, and outputting, based on the one or more measurements, a control instruction that causes the control action to be performed. The method includes receiving the one or more measurements from the wearable device being worn by a user, determining whether the one or more measurements indicate, during an interval training session, that one or more characteristics of the user are within a desired target zone, and responsive to determining that the one or more measurements indicate the one or more characteristics of the user are not within the desired target zone during the interval training session, performing the control action.

The present invention relates to a self-ambulation helper and assistive rehabilitative device that is primarily designed to train the initial developmental phase of early life i.e., independent crawling. The device includes a tummy rest, a pair of forearm rest, a pair of leg rests, a left supporting rod, a right supporting rod, and a main frame. The tummy rest includes a tummy bracket, a top layer, and a pair of height adjusting mechanisms. The pair of forearm rest includes a left forearm rest and a right forearm rest. The pair of leg rest includes a left leg rest and a right leg rest. Each forearm rest and each leg rest include an adjustable strap and a base support. The device ensures reinforcement of biomechanically correct training patterns through repetitive practice at home for such patients.
