An elastic band for use in a resistance-type exerciser. The elastic band includes a continuous loop of elastic material having a pair of receiving portions and a pair of spanning portions extending between the pair of receiving portions. A cross-sectional area of each receiving portion is greater than a cross-sectional area of each spanning portion.

A wheel exercising device includes a shank, two handgrips, two wheels, and two caps. The shank has a first threaded section and a second threaded section having different screwing directions. Each of the two handgrips is formed with an internal threaded section screwed onto the first threaded section and the second threaded section of the shank. At least one elastic member is connected between the two handgrips. Each of the two wheels is mounted on the shank. Each of the two caps is mounted on the shank and rests on one of the two wheels. When the two wheels are rotated forward and backward, the two handgrips are moved inward and outward synchronously along the first threaded section and the second threaded section of the shank.

In one embodiment, an exercise system includes a user interface device sized and configured to fit within a user's hand, the user interface device including a microcontroller configured to control operation of the device, a first sensor configured to sense movements of the device, a second sensor configured to sense forces applied to the device, and a communication device configured to communicate data concerning the sensed movements and forces to a separate device.

A wheel exercising device includes a shank, at least one wheel mounted on the shank, two handgrips mounted on the shank, two mounting rings mounted on the shank, and two caps mounted on the shank and resting on the mounting rings. The shank has a first threaded section and a second threaded section having opposite screwing directions. Each of the handgrips is formed with an internal threaded section screwed onto the first threaded section and the second threaded section. Each of the handgrips is formed with a connecting ring, and at least one elastic member is connected between the connecting ring of each of the handgrips and each of the mounting rings. In practice, when the wheel is rotated forward and backward, the handgrips are moved inward and outward synchronously along the first threaded section and the second threaded section.

A physical exercise apparatus according to an exemplary embodiment of the present disclosure includes a frame, a seat, a pair of movable arms, and a pair of cycling foot pedals. The seat may be supported by the frame and configured to support a user in an at least partially supine position. The pair of movable arms may be movably coupled to a first portion of the frame and coupled with a common, linearly movable resistance load. The first portion of the frame may be stationary with respect to the seat. The pair of cycling foot pedals may be movably coupled to a second portion of the frame and independently movable from the pair of movable arms so that the user can cycle the pair of cycling foot pedals while separately engaging the pair of movable arms.

There is provided an exercise machine. The machine includes an upright mounting assembly having a top and a bottom spaced-apart from the top. The machine includes a seat operatively connected to the mounting assembly. The machine includes a first pair of space-apart pulley assemblies rotatably mounted adjacent to the top of the mounting assembly. The machine includes a second pair of spaced-apart pulley assemblies rotatably mounted adjacent to the bottom of the mounting assembly. The machine includes a plurality of exercise resistance cables connected at proximal end portions to the mounting assembly and extending around and outward from the pulley assemblies.

An exerciser and an elastic band. The exerciser includes first and second arms, a connector, and at least one elastic band. The first arm has a first body portion and first and second ends extending from the first body portion. The first body portion includes a first elongate slot and a first hinge portion disposed on opposite sides of the first body portion. The exerciser includes a second arm having a second body portion and first and second ends extending from the second body portion. The second body portion includes a second elongate slot and a second hinge portion disposed on opposite sides of the second body portion. The exerciser includes a connector rotatably coupling the first and second hinge portions of the respective first and second arms. The exerciser includes at least one elastic band formed as a continuous loop and disposed within the first and second elongate slots.

An exercise machine is provided for developing the chest muscles while maintaining correct biomechanical posture and joint movement for the user, thereby maximizing efficiency and safety. The exercise machine includes a track on which two platforms independently slide. The platforms are each interconnected to a weight stack unit or other vertical resistance unit that provide resistance to the inward movement of the platforms. Each platform may also be connected to a tension element or resistance band that is configured to provide gradual and progressively increased resistance as the platforms are moved inwardly towards the center or center stop of the track.

Disclosed is a rehabilitation training apparatus including a pair of first tracks that are arranged in parallel at an interval, a second track that is perpendicular to the pair of first tracks and is movably connected to the pair of first tracks, a hand holder that is movably provided in the second track and on which a hand of the user is held, a holder driving unit that reciprocally moves the hand holder along the second track, and a track driving unit that reciprocally moves the second track along the pair of first tracks.

Disclosed is a rehabilitation training apparatus. The rehabilitation training apparatus includes a pair of first tracks that are arranged in parallel at an interval, a second track movably connected to the pair of first tracks, a hand holder that is movably provided in the second track and on which a hand and an arm of a user is held, and a stopper for a track provided in at least one of the first tracks and the second track to limit movements of the second track and the hand holder.
