An active suspension orthotic support system is disclosed. The suspension orthotic support system comprises at least one variable resistance beam extending from a heel section to a mid-arch section of the footwear, wherein rotation of the variable resistance beam from a first position to a second position causes a resistance provided by the variable resistance beam to vary between a minimum resistance to a maximum resistance.

In one example, a muscle exercise device includes a first arm, a second arm rotatably connected to the first arm, and the second arm and first arm configured to cooperatively define a recess. The muscle exercise device also includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm, and a wireless transmitter disposed in either the first arm or the second arm, wherein the wireless transmitter is responsive to communications from an app residing on a user device.

An exercise rod for supporting an exercise elastic rope includes a supporting member rotatably sleeved on the exercise rod. The periphery of the supporting member is provided with an annular positioning groove for cooperating with a hook. An end of the exercise rod is detachably provided with a blocking member configured to prevent the supporting member from separation, a retractable blocking button is arranged adjacent to the end of the exercise rod, and the supporting member is limited between the blocking button and the blocking member. The supporting member is rotatably sleeved on the exercise rod, and the supporting member is provided with a positioning groove matched with the hook. When the hook is subjected to force, the relative movement between the hook and the supporting member is transformed into the rotation of the supporting member, thereby eliminating the sound caused by friction and collision between parts.

A cycling device used for exercise and/or rehabilitation includes a shaft for grasping by a user, a foot assembly coupled to the shaft and configured to be supported on a surface, and a pedal assembly coupled between the shaft and the foot assembly. The cycling device is intended to be used by a seated user.

An apparatus for exercising the muscles. The apparatus includes an exercising device having a power arm or lever, which can be equipped with actuating elements at a first end of the power arm or lever. A second end of the power arm or lever is arranged on a retaining element in a way pivotable about a pivot axis at a first articulated joint. A compression-spring element can be articulated, by way of a first end of the compression-spring element at a first point of articulation on the power arm and articulated, by way of a second end of the compression-spring element at a second point of articulation on the retaining element. A cable-pull arrangement has a cable and is fixed in a releasable manner in a spatial relationship to the exercising device, independently of the exercising device, by means of a first fixing device and is able to be combined with the power arm of the exercising device by means of a second fixing device, so that the cable-pull arrangement is connectible to the exercising device in order for training to take place.

In one example, a muscle exercise device includes a first arm and a second arm rotatably connected to the first arm, and the second arm and the first arm are configured to cooperatively define a recess having a shape that changes as one of the first arm and the second arm moves toward, or away from, the other of the first arm and the second arm. The muscle exercise device further includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm so as to assume a configuration similar to the shape of the recess. Finally, a wireless transmitter chip is disposed in either the first arm or the second arm, and the wireless transmitter chip is responsive to communications from an app residing on a user device.

An exercise machine is disclosed. The exercise machine comprises a tension generating device. The exercise machine comprises a translatable arm mount coupled to the tension generating device. The exercise machine comprises an arm coupled to the translatable arm mount. The exercise machine comprises a cable coupled to the tension generating device via the arm.

An arm extension apparatus comprising a propulsion blade comprising a top half and a bottom half, wherein the top half is generally straight and wherein the bottom half comprises a curve, and wherein the bottom half comprises a proximal end and a distal end, and wherein the distal end comprises a foot, and wherein the foot comprises two split toes.

A fitness machine operable by a user. The fitness machine includes a base that extends in a length direction, a width direction, and a height direction that are perpendicular to each other. A mobile portion is configured to support the user during operation of the fitness machine. A resilient body is configured to provide a resistance against the mobile portion moving towards the base in the height direction. A frame is moveable in the length direction relative to the base to adjust the resistance provided by the resilient body. A fastener assembly moveably couples the frame to the base, where the fastener assembly is configured to expand in the width direction to prevent the frame from moving in the width direction relative to the base during operation of the fitness machine.

An extendable fitness bar including an internal elastic member. The device includes two, hollow external bars with ends facing one another. On the interior of the two external bars is an internal bar and an elastic member that extends through the two external bars and the internal bar. The elastic member is attached to the far end of the first external bar and the second external bar. The user can grasp each external bar and separate them, exposing the interior bar and creating a longer continuous bar. This separation also causes the elastic member to stretch creating tension. The user may also twist the two bars in opposing directions (clockwise and counterclockwise) for additional stretches.
