An apparatus for an exercise task includes a pneumatic arrangement, which includes a pressure source, a pneumatic controller, pneumatic transfer channels, and at least one pneumatic resistor element, which includes a pneumatic cylinder with its piston. The apparatus additionally includes a mechanical lever arm structure or another mechanical connecting structure, which is for a user's limb contact and which is at a second end connected to the pneumatic resistor element. The apparatus additionally includes a sensor structure, a calculation arrangement and a display. The sensor structure is arranged to measure at least one measurement quantity of the exercise task and, based on the measurement, the calculation arrangement is arranged to form information on the display of the apparatus, regarding the power and/or force and/or range of motion of the exercise task. In the invention, regardless of the number of pneumatic resistor elements, the sensor structure includes one pressure sensor only, and to compensate for the small number of sensors, the calculation arrangement includes a correlation-taught calculation unit, which comprises a correlation algorithm taught with a larger number of sensors than the number of sensors in the apparatus, concerning the correlation between power and/or force and/or range of motion of the exercise task and the measured information.

A foldable exercise device with a chin-up exercise apparatus and a dip exercise apparatus suspendable from the chin-up exercise apparatus. The chin-up exercise apparatus has a top horizontal member and a bottom horizontal member connected by two connecting members. Each connecting member has a door header hook and a parallel chin-up handle that rotate on the connecting member from a flat configuration to an exercise configuration. In the exercise configuration the chin-up exercise apparatus can engage a door frame. In the exercise configuration the parallel chin-up handles can be used for neutral chin-ups. The dip exercise apparatus has two vertical members spaced apart by a horizontal connecting member. The vertical members have a bottom end with a bottom grip. The bottom grip can be rotated from a flat configuration to an exercise configuration. In the exercise configuration the bottom grips can be used to do dip exercises.

The present invention relates to wobbly balls and exercise coil springs. A wobbly ball may include a non-spherical rigid, hollow ball body formed of two halves, each half comprising an upper ladle or a lower ladle which are welded together along a central seam therebetween, and defining a hollow cavity therein. A spherical inner ball is captured within the hollow cavity of the hollow ball body of the wobbly ball, so that upon movement of the wobbly ball, the inner ball rolls within the cavity, producing a wobbly, eccentric motion. The exercise coil spring may be formed of a single coiled wire, the coiled spring including a central portion where the coiled wire is coiled to a first diameter that is constant. Opposed flared ends are provided ends of the central portion where the coiled wire is progressively coiled from the first diameter to a second diameter, which is greater.

A cam mechanism may include a cam assembly rotatably mounted to an axis shaft and having a profile arc adapted for receiving a belt or cable, a belt adjustment lever pivotally mounted to the cam assembly and having a control bearing, and a cam range slot plate rigidly mounted to the axis shaft and defining a slot in sliding communication with the control bearing of the belt adjustment lever, wherein the belt adjustment lever is connected to one end of a belt or cable, and the opposite end of the belt or cable is connected to a moveable weight stack, and wherein the cam assembly is rotatable relative to the cam range slot plate.

A training device (1) for training abdominal muscles comprising an arm (3) and a handle (2) for holding with two hands, the handle (2) being attached to or forming an integral part of the arm (3). There are disclosed different embodiments allowing a user to hold the handle (2) and to make arch-like training movements in order to train control of abdominal muscle activity.

An exercise machine accessory system for facilitating exerciser rehydration during a workout and antibacterial machine wipe down. The exercise machine accessory system generally includes an exercise machine having a first end and a second end, first and second stationary exercise platforms, a movable carriage movably positioned upon a rail, a biasing member connected to the movable carriage, first and second handle assemblies connected to the frame of the exercise machine, a first bottle holder, a first antibacterial wipes dispenser and/or a first disposal receptacle connected to the first right handle assembly or the first left handle assembly.

A handstand pushup device has a central body portion that includes a padded cushion, and two handplates, positioned laterally on opposite sides of the central body portion. Each of the handplates has a flat upper surface that is slip resistant. Two elongate blocks are also provided, each of the elongate blocks having a bottom surface and an inner surface. The bottom surface interlocks with the one of the handplates for removably mounting the elongate block on the handplate. The inner surface of the elongate blocks limits the placement of a user's hands while performing handstand pushups using the device, so that the user's hands are not placed too far apart when performing the handstand pushups.

A rear handlebar assembly in combination with a seat and a supporting member of a stationary bike, includes a seat of a stationary bike for supporting a rider thereon. A supporting member supports the seat of the stationary bike. A joining member includes a vertical bore and a horizontal bore, the vertical bore receiving therein the supporting member, the horizontal bore receiving therein a shaft coupled to flanges of the seat. A clasp holds the joining member against the supporting member. A crossbar forms a rear handlebar adapted to support the hands of a rider in an upright riding position. A rearwardly extending member connects the joining member to the crossbar. A pair of hand grips can be positioned on the crossbar.

A force measurement device has a motion dampening device having at least two ends. A first end is releasably engaged to a base frame and a second end is releasably engaged to a moveable member. A load cell is in communication with the motion dampening device. The load cell measures a force imparted by a user and the load cell registers the force to a display which depicts the registered force exerted by the user. A method for measuring the force a user imparts onto an exercise apparatus comprises the user imparting force onto a moveable member. The motion dampening device imparts a force substantially opposite to the user force and a load cell measures the force exerted by the user. The force is transmitted to a display wherein the display depicts the registered force imparted by the user.
