Abstract: Conventional skipping ropes have a generally elongate handle swivellably mounted on each end of the rope which is held by the user between the fingers and palms. In accordance with the invention, the handle is shaped like a “T” with the vertical stroke of the T being, at one end, swivellably connected to the rope, and also being, at the other end, connected to the crosspiece, a.k.a. transverse portion, of the T. The handle may be held with the crosspiece of the T situated between fingers and palm and with the vertical “stroke”, a.k.a. elongate portion, extending between two fingers. The crosspiece a.k.a. transverse portion of the handle is asymmetric, and thereby adapted to fit to a hand which is holding the handle with the vertical a.k.a. elongate portion passing between two fingers other than the second (index) and third (middle) fingers.

Abstract: A shoulder press exercise machine has a main frame, a user support pivotally mounted on the frame for supporting a user in a seated position, at least one exercise arm movably mounted on the frame and movable between a start position in which handles are located in front of the shoulders of a user on the user support frame and an end position in which the handles are located above the head of the user. A connecting linkage connects movement of the exercise arm to movement of the user support, so that movement of the exercise arm from the start to the end position simultaneously rotates the user support. A load resists movement of at least one of the moving parts of the machine. The combined motion of the user, user support frame and exercise arm between the start and end position substantially replicates the natural movement of the upper part of a human body when performing a free weight shoulder press exercise.

The exercise resistance cable apparatus includes an elastic exercise resistance cable. A cable anchor ring is securely connected to a first end of the elastic exercise resistance cable. A handgrip is connected to a second end of the elastic exercise resistance cable. During use the elastic exercise resistance cable is directed through an activity bay of the pulley assembly and ultimately attached, via the cable anchor ring, to the cable locking pin of the anchor assembly of the support structure. The exercise resistance cable apparatus is particularly adapted to be used with an exercise chair having a frame with pulley assemblies defining a plurality of activity bays positioned at desired locations thereon.

Abstract: A revolution counter for wrist exerciser includes a generator module, at least a detection element pair, a wireless transmission module, and wireless receiver. The generator module, the detection elements, and the wireless transmission module are arranged between a rotor and a stationary casing of the wrist exerciser. The rotation of the rotor with respect to the casing induces a voltage in the generator module, which is supplied to the detection elements and the wireless transmission module. The detection elements detect the rotation of the rotor and generate a signal associated with data of the rotation to the wireless transmission module. The wireless transmission module converts the signal into corresponding data and transmits the data in a wireless manner. The wireless receiver receives the data and displays the data in a display device or transmits the data to an external electronic device.

Abstract: An exercise arm apparatus has a stationary frame member, a first pivoting arm pivoted to the frame member at a location intermediate its ends for rotation about a first pivot axis, a second pivoting arm pivotally connected to the frame member for rotation about a second pivot axis spaced from the first pivot axis, and a connecting link pivotally connected to the first arm and second arm to form a four-bar linkage. The first arm is an exercise arm with handles at one end for gripping by a user, and the connecting link is of sufficient weight to form a counter-weight to counter-balance the first exercise arm into a rest position corresponding to a start position for an exercise movement. In one example the connecting link is a solid, elongate bar of heavy metal or equivalent material.
