An exercise device includes a foot support portion pivotably connected to a leg support portion and having a neutral position relative to a pivot axis. The support portion is configured to rotate about the neutral pivot axis in a first direction away from the neutral position and in a second direction away from the neutral position. The second direction is opposite the first direction. The exercise device also includes a resistance mechanism configured to exert a force on the foot support portion about the pivot axis opposite to the respective first and second directions of rotation of the foot support portion about the pivot axis.

The invention relates to a gymnastics and therapy multifunctional installation by realizing rocking movements of the human body, wherein the installation comprises, configuration of liquid-containing spaces (1) by placing adjustable walls (2) with integrated support bars (3), a frame support base (4) in which a variable support frame is mounted, movable holders (52) mounted on the support frame and on the support bars (3) for mounting support components of the human body and cables (9), wherein on cables (9) a substrate base (10) is connected for the assembly of a substrate consisting various parts, where hand (16) and feet (15) parts of the substrate are used separately for exercises. A multifunctional device realizes the rocking movements by generating wave and currents through alternative components assembled into a chamber (24), transmitting movement in various system components and moving through arms (34) the frame support base (4) and support bars (3).

A resistance system, which can be suitable for incorporation in exercise equipment, is a hybrid resistance assembly having at least a first and a second resistance unit. The first resistance unit can be of a first type and the second resistance unit can be of a second type. The first resistance unit can be an inertial resistance unit, which incorporates an inertial load that creates resistance influenced by the inertia of a movable mass, such as a rotatable flywheel. The second resistance unit can be a static or non-inertial resistance unit, such as a displacement resistance unit, which incorporates a load that creates resistance influenced by displacement (e.g., linear or rotational displacement) of an input to the displacement resistance unit.

A weight sled for fitness training that uses a plurality of separately-adjustable resistance mechanisms to allow for adjustment of overall resistance, bias correction and directional control, and wheel skid or slippage control, by means of differential adjustment of the resistance of the plurality of resistance mechanisms. Differential adjustment of the resistance mechanisms can be used to manually or automatically offset a directional bias in the sled, ground surface, or the athlete's abilities to keep the sled moving in a linear motion, and to prevent wheel skid on surfaces with differing friction coefficients.

An exercise apparatus for use by a sole individual user. In the preferred embodiment, a frame having a base is provided. A mast is attached to the base. A pivotable platform or bench on which the user can be positioned is operatively connected to the base and, in the quiescent state of the apparatus, parallel to the base. A handlebar unit, preferably comprising two grips, is connected to the mast, the handlebar unit having at least one sensor operable by the individual user. A drive element is operatively connected to the mast for producing resistance to the handlebar unit. The exercise apparatus operates on the principle of negative resistance technology, so when the user releases at least one of the handlebar unit sensors, the handlebar unit returns to an initial position relative to the mast, and the user can rest, start again, or depart from the apparatus.

An exercise apparatus allowing freedom of movement of an exercise bar is provided. The exercise apparatus comprises one or more base assemblies; a pair of spaced vertical members mounted to the one or more base assemblies; and a first bar member mounted to the spaced vertical members, wherein the first bar member is at least partially rotatable relative to the longitudinal axes of the vertical members. The one or more base assemblies may facilitate multidirectional horizontal movement of the vertical members, whereby the first bar member is rotatable relative to the longitudinal axes of the vertical members.

A resistance system for a rowing machine has a mounting bracket, a housing assembly, a paddle wheel, a driving assembly and a restoring assembly. The housing assembly is mounted on the mounting bracket and includes a liquid tank for storing liquid. The driving assembly is connected to the paddle wheel and drives the paddle wheel to rotate in a direction only. The restoring assembly is connected to a strip hub of the driving assembly and is able to drive the strip hub to rotate in a reverse direction. The resistance system for the rowing machine has simplified structure. Therefore, it is easy to assemble to the resistance system, and manufacturing cost of the resistance system can be decreased. In addition, a service life of the resistance system as well as the rowing machine can be increased.

An exercise machine which is capable of having its lift, roll, or pitch adjusted with respect to a base so as to provide a plurality of positions of the exercise machine with respect to the base. The exercise machine generally includes a base and an exercise machine movably connected to the base. The exercise machine may include a track, a carriage slidably connected to the track, and a biasing member attached to the carriage to apply a resistive force to the carriage. A plurality of actuators may be connected between the base and the exercise machine. The plurality of actuators may be utilized to adjust a pitch angle or a roll angle of the exercise machine with respect to the base. The plurality of actuators may also be utilized to lift or lower the exercise machine at a constant angle of pitch and/or roll inclination.
