The object of the invention is an apparatus suited for individuals in training dynamic balance and turning maneuvers while walking, said apparatus allowing said maneuvers while an individual is standing, walking on a flat surface or walking on a treadmill that can rotate around a vertical axis of the treadmill. To serve this purpose, the apparatus of the invention is provided with a base platform (1), in which two universal joints (2,2) are arranged that are connected with a pelvis element (5) with two vertical rods (3,3) or vertically adjustable rods (30,30) via conventional spherical joints (4,4), and the universal joints (2,2) have two degrees of freedom that can further be provided by drives (6,7,8).

An adjustable-length jump rope device that provides the benefits of a speed rope and weighted rope in one device by, among other things, allowing the rotational resistance of the jump rope to be varied without affecting the circumference of the rope and by distributing the weight of the rope evenly, thus, enabling smooth and natural jumping.

An exercise chair that is operable to engage a user's core muscle groups in order to maintain a desired position thereof. The exercise chair includes a base having a plurality of legs. A seat member is rotatably secured to the base. A first mounting plate is secured to the bottom of the seat member. A second mounting plate is secured to the first mounting plate. The second mounting plate is ring-shaped and undulated in form having at least two peak section and at least two valley sections. A wheel assembly is superposed the base and includes wheels configured to engage the second mounting plate and traverse therealong. A mount having a shaft coupled thereto rotatably couples the seat member with the base. In a first position of the exercise chair, the wheels of the wheel assembly are engaged with the at least two peak sections.

An exercise machine may include a frame with set of foot pedals mounted thereon. A seat-receiving space is defined by the frame rearward of the set of pedals and a seat that is in the form of an inflatable bladder is received within the seat-receiving space. The inflatable bladder is retained within the frame in such a way that the bladder is able to move within the frame when the exercise machine is used. A seat back extends upwardly of and adjacent the inflatable seat and supports a user's back while the user is seated on the inflatable seat. Left and right arms are secured to the frame and extend respectively to the left and right of the inflatable seat. The user may undertake a cardiovascular workout and a core workout of abdominal and back muscles using the exercise machine.

The present invention is intended to provide an active exercise apparatus for lower limbs that allows a user to perform on a floor lower limb active exercise highly effective in preventing thrombosis. An active exercise apparatus for lower limbs 10 includes, for example, a base body 1; a shaft 2 fixed to the base body 1 such that a central axis is vertical to the surface of the base body 1; arms 3a and 3b that are rotatably attached to the shaft 2 and are extended in two directions at an equal angle with respect to the central axis of the shaft 2; sole support plates 4a and 4b that are attached to leading ends of the arms 3a and 3b and rotatable by rotation axes x.sub.1 and x.sub.2 parallel to the surface of the base body 1 and the rotation axes z.sub.1 and z.sub.2 vertical to the surface of the base body 1; and reaction force exertion members that are installed on the back surfaces of the sole support plates 4a and 4b to exert a reaction force on backward rotation by rotation axes x.sub.1 and x.sub.2 parallel to the surface of the base body 1.

Exercise equipment and toys are provided for a portable piece of exercise equipment that enables a user to perform a cardiovascular workout and develop the abdomen simultaneously. Further, the exercise assembly does not require electrical power to operate, but rather operates from the momentum generated by the user. The user generates momentum by pumping the arms, which crates rotation that twists the torso in a reciprocating path, i.e., left-to-right. Thus, the assembly may be portable, non-powered, and configured to enable both cardiovascular and abdominal workouts through a twisting motion, and from a standing, kneeling, or sitting position.

A device for moving the back and core muscles while sitting includes a rocking assembly that sits atop a base assembly, and optionally a height adjustment mechanism between the rocking assembly and the base assembly. The rocking assembly further includes a rocking mechanism that sits between a base plate or platform and a seat. The rocking mechanism can be, for example, a hollow or solid hemispheric- or dome-shaped rocking mechanism, an eccentric bicylinder rocking mechanism, and/or a rocking mechanism based on an arrangement of halfpipe members. The rocking mechanisms of the exercise chair allow to the seat to rock, wobble, and/or swivel with a side-to-side rocking motion, a front-to-back rocking motion, or both a side-to-side rocking motion and a front-to-back rocking motion.

Improved exercise machines having a movable user engagement member and a user support movably mounted on a movable slide support surface and a slidable wedge concurrently engaging the movable slide support surface and a stationary slide support surface and an operative linkage system connecting the user engagement and the slidable wedge such that movement of the user engagement causes the slidable wedge to engage the slide support surfaces changing the distance between at least a portion of the slide support surfaces and thereby creating a multi-dimensional articulating movement of the user support during an exercise motion.
