An exerciser, preferably in the form of a stepper with a fluid resistance system guides stepper treadles angularly downward and outward from the center of the stepper. According to an embodiment bellows that support treadles angle downward and outward.

An electromechanical device for simulation of physical exercise with legs and arms includes two pedals mounted on two contiguous pantographs, with parallel supporting arms that are positioned in a predominantly vertical sense, with an orthogonal junction and parallel arms which are articulated, in a predominantly horizontal sense, onto the frame of the device and which always move in opposing directions left and right, through traverses which are articulated on vertical and horizontal axles, respectively, connected to vertical and horizontal parallel bars by means of risers.

A pedaling vibrational apparatus includes a seat body, a pedal assembly, a gear plate assembly, a drive assembly and an eccentric assembly, like a lever structure. By treading the pedal assembly, the gear plate assembly drives the drive assembly to rotate. The drive assembly is connected with the eccentric assembly. A user can fully exercise muscles of the user's body during exercise, and a vibrational effect generated by the eccentric assembly can stimulate acupuncture points of the user's body to improve blood circulation. Left and right pedals of the pedal assembly can be treaded in turn to continuously drive a gear to rotate in a same direction so as to achieve an effect of acceleration and to enhance vibrations.

A device for the therapeutic treatment and/or training of the lower extremities of a human having driven and controlled movement devices, which are connected to a stationary frame and include holding members for fastening of one extremity. The holding members can be moved independently of one another along walking trajectories. The movement devices each include a pivot arm pivotable into different elevations, and the pivot arm is rotatably connected to one single sled on a linear track. A first rotational drive is attached to a single sled and is connected to the pivot arm for changing the elevation of the respective holding member. The pivot arm includes a second rotational drive for changing the inclination of the respective holding member and the sled is connected to a linear drive for changing the longitudinal position of the respective holding member.

A swingable exercise bike includes a base having a first pivot portion for a bike body to be pivotally connected to the first pivot portion so that the bike body can swing left and right relative to the base. Left and right sides of the first pivot portion are provided with first connecting rods. The first connecting rods each have one end pivoted to the base and another end extending in a height direction and pivoted to a second connecting rod. The second connecting rod is further pivoted to the bike body. When the bike body swings left and right, the first and second connecting rods are pivoted. The two second connecting rods are connected with a cushion device disposed in a horizontal direction, which can generate a damping effect when the two second connecting rods are pivoted by the bike body, thereby cushioning the swing of the bike body.

A stepper exercise apparatus may include a frame pivotally supporting two pedals connected to the frame. Two cylinders are pivotally connected to the two pedals and to the frame. The pedals may be interconnected to move in coordinated movement in opposite directions. The cylinders provide exercise resistance to the force alternatively applied to the pedals by the user. An exercise resistance adjustment assembly may be actuated to adjust the exercise resistance setting of the stepper exercise apparatus.

A pedal-type vibrational apparatus includes a seat body, a pedal assembly, a gear plate assembly, a drive assembly and an eccentric assembly, like a lever structure. By treading the pedal assembly, the gear plate assembly drives the drive assembly to rotate. The drive assembly is connected with the eccentric assembly. The user can fully exercise the muscles of the body during exercise, and the vibrational effect generated by the eccentric assembly can stimulate the acupuncture points of the body to improve the blood circulation. The left and right pedals can be treaded in turn to continuously drive a gear to rotate in the same direction so as to achieve the effect of acceleration and to enhance vibrations.

A collapsible exercise stepper contains: a base, a movable extension rack, a grip assembly, two stepping units, two hydraulic cylinders, and a folding unit. The base includes a first fixing rod and a first connection rod, and the first fixing rod has a first coupling portion. The movable extension rack includes a second fixing rod and a second connection rod with a second coupling portion and two extending tabs, wherein the second connection rod has a horizontal bar and a third coupling portion. The grip assembly rotatably includes a handle, a fitting tube, an accommodation portion, and an actuation seat. Each stepping unit includes a support plate and a pedal, wherein the support plate has a rotation portion and a driving portion. Each hydraulic cylinder includes a first joining portion and a second joining portion. The folding unit includes a first operation element and a second operation element.

Embodiments of an exercise machine are disclosed. In one embodiment, an exercise machine includes a base frame, a pair of left and right pedal assemblies, and a pedal supporting assembly. The base frame is adapted to be positioned on a support surface. The left and right pedal assemblies have a pair of left and right pedals, and each is positioned over and rotatably supported by the base frame. The pedal supporting assembly is attached to the base frame and configured to pivot around an axis. The pedal supporting assembly also supports the left and right pedal assemblies. The pedal supporting assembly is operable to generate resistance in response to movement of the left and right pedals and the pedal supporting assembly pivoting around the axis.
