The present invention describes an electromechanical exercise machine that simulates the inertia and weight of a mass in Earth's gravity field and allows a user to move said simulated mass in the primary degrees of freedom of a traditional barbell free-weight system, with or without the use of various accessories.

An upright bike includes a main frame including a front portion and a rear portion. A rail structure is connected to the rear portion of the main frame. An X-shaped frame is slidably mounted to the rail structure and pivotally connected to the front portion of the main frame. A slide end is formed on the X-shaped frame and slidably mounted onto the rail structure. A stepping structure is mounted on a lower section of the first trestle of the X-shaped frame. A seat is secured on a top of the first trestle of the X-shaped frame. A handlebar is transversally secured on the X-shaped frame. A restitute element has two opposite ends respectively secured on the first trestle and the second trestle of the X-shaped frame for providing restitution force to the X-shaped frame when the handlebar is upwardly pulled.

A compounded fitness trainer, including a base, on which a loading device is pivoted; a pair of first driving bars pivoted on the base for swinging; a pair of second driving bars pivoted on the base for swinging; a pair of first linkages respectively pivoted on the second driving bars and opposite sides of the loading device; and a pair of second linkages respectively pivoted on the first driving bars and the first linkages wherein the first driving bars are moved by the second driving bars when the second driving bars are moved, and the second driving bars are moved by the first driving bars when the first driving bars are moved whereby moving the first driving bars and/or the second driving bars may train different muscles.

A rowing machine to simulate the action of rowing a watercraft includes an energy damper, a handle, and a tensile member connecting the handle to the energy damper. The handle includes a grip member with a right hand grip and a left hand grip, and a connecting member connected to the tensile member. The connecting member is configured to transmit a force from the tensile member to the handle such that the force is substantially centered between the left hand grip and the right hand grip. The grip member is configured to rotate relative to the connecting member and provide at least one of a haptic indication and an audible indication when the grip member rotates relative to the connecting member from a first position to a second position that is substantially ninety degrees from the first position. The simulation may include actions to replicate feathering an oar.

A two-way row machine includes a base frame arranged to be in contact with the bottom surface; a standing frame coupled to the upper surface of the base frame and arranged to stand in the vertical direction; a footrest unit seated on the upper surface of the base frame and supporting a user's feet; a support unit fixed to the standing frame and the footrest unit, supporting a user's body, and adjustable in standing angle and height; a pair of rotation units link-coupled to the base frame and disposed inclined toward both lower sides of the support unit; a pair of handle units coupled to one end of each of the pair of rotation units, formed for the user to hold it to rotate the rotation unit, and adjustable in angle; and a pair of rotation stopper units coupled to the base frame.

The present invention provides an apparatus for the gymnastic exercise of paddling simulation, comprising a frame (1) which includes aa front part and a rear part, a housing region (11) for a user (4) within said frame (1) at said rear part of said frame (1), a kinematic mechanism (3) connected to said frame (1) via supporting means (2,10) onto said frame (1), wherein said supporting means (2,10) are connected with the said frame (1) in aa lockable tiltable manner, said kinematic mechanism (3) includes two crank mechanisms (30), wherein each crank mechanism (30) is mounted on said supporting mechanism (2,10) via aa respective supporting base (31), and wherein each crank mechanism (30) is capable of rotating about aa rotation axis (Y-Y) via a respective rotation shaft associated with said supporting base (31), and wherein said kinematic mechanism (3) is kinematically connected with a mechanical resistance means (23) via transmission mechanism (22,37), the apparatus is characterized by the fact that said supporting base (31) is mounted on said supporting means (2,10) in a tiltable and lockable manner, the arrangement being such that each rotation axis (Y-Y) of said crank mechanism (30) forms a predetermined angle with respect to said supporting means (2,10) following a locked arrangement of said supporting base (31) on said supporting means (2,10).
