An exercise device is described which includes a platform having a first end and a second end opposite the first end; first and second wheels, wherein the first wheel is positioned proximate the first end and the second wheel is positioned proximate the second end and the first and second wheels are configured to roll across a surface as the exercise device is displaced along the surface; a first motor configured to apply a first torque to the first wheel where the magnitude of the first torque is related to the distance of the exercise device from a zero position and the direction of the first torque urges movement of the exercise device toward the zero position. Versions are also described with more wheels and more motors.

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.

The present invention relates to an exercise method and an exercise device for performing an exercise suitable for thigh and hip muscles like fitness equipment or an exercise bicycle, and more particularly, to an exercise method and an exercise device for strengthening thigh and hip muscles by performing a movement of lowering legs and then moving the legs backward or putting the legs together or apart from a position of pulling the legs toward a chest of the user with an arm disposed between the legs in a sitting or lying position of the user. In addition, the present invention relates to a leg exercise device including a trajectory measuring device of generating motion range information of the exercise device and making the motion range information as data through a motion range measurement sensor attached to a knee and a hip joint of the user seated on the exercise device, smart device and an application of the smart device.

A safety trampoline, including a trampoline frame, trampoline supporting legs, a jumping mat, springs and an elastic protective sleeve, wherein the jumping mat is connected to the trampoline frame through the springs; a periphery of the jumping mat is connected to connecting rings; the elastic protective sleeve is ring-shaped; a plurality of net holes are formed at a first end of the elastic protective sleeve; the connecting rings pass through the plurality of net holes to clamp the elastic protective sleeve between the springs and the jumping mat; and a second end of the elastic protective sleeve is turned to a bottom of the trampoline frame and an edge thereof is tied to cover upper parts of the springs. Through an arrangement of the elastic protective sleeve, the elastic protective sleeve and the jumping mat, or the elastic protective sleeve, the jumping mat and a trampoline pad are integrally connected.

A variable resistance exercise device is provided that comprises a pair of arm bands and a handle tube that has a longitudinal interior bore. The tube has first and second ends and includes a solid metal center shaft fitted through the interior bore thereby exposing respective first and second end portions of the shaft at the respective first and second ends of the tube. The first and second band arm of the pair of bands arms are respectively fitted onto the first and second ends of the shaft. In some instances, the device is part of a kit that includes a base having a bottom face, where the bottom face includes a groove, and one or more elastic bands, each such band configured to removably couple the base to the exercise bar by fitting the into the groove of the base and through the first and second arm bands.

An exercise device with controllable training modes includes a base, a first exercise mechanism, a second exercise mechanism, and an operating mechanism. The first exercise mechanism has a first gear member. The second exercise mechanism has a second gear member. The operating mechanism has a third gear member. When the third gear member is at a first position, the third gear member meshes with the first gear member and the second gear member to form a linked state, so that the first exercise mechanism and the second exercise mechanism are operatively linked and coupled and swing in opposite directions. When the third gear member is at a second position, the third gear member is disengaged from either the first gear member or the second gear member or both to form a free state, so that the first exercise mechanism and the second exercise mechanism individually swing.

An exercise device with a base on a support surface and a user platform. One end of a support post is axially mounted to the base and the other end is pivotally mounted to the platform. The platform pivots with the post in a horizontal plane parallel to the support surface and pivots in a vertical plane perpendicular to the support surface. A resistance element having one end mounted to the support post and the other end to the base is provided to control the velocity and angle of pivot of the platform in the horizontal plane. A resistance element having one end mounted to the base and the other end to platform to control the velocity and angle of pivot of the platform in the vertical plane. The user stands on the platform and performs exercise motions to propel the platform in the horizontal plane and the vertical plane.

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.

The apparatus provides an exercise device that is portable, versatile, and enables the user to match the resistance of the device with the normal physiologic length-tension relationship of skeletal muscle. The device adds resistance in the form of cartridges that are stackable to summate resistance and can connect to a variety of attachments for use with arms, legs, or trunk, i.e., handle, bar, loop, etc. Given the device’s portability, it can be used freestyle or mounted to various surfaces.

A fitness device comprises a force applicator comprising: a base; a first fixed wheel comprising a first center pivotally fixed to the base, and configured to allow rotation of the first fixed wheel about the first center; a second fixed wheel comprising a second center pivotally fixed to the base, and configured to allow rotation of the second fixed wheel about the second center, wherein the second fixed wheel is substantially in line with the first fixed wheel; and a movable wheel positioned above and between the first fixed wheel and the second fixed wheel, and comprising a movable center configured to move either toward, or away from, the first fixed wheel and the second fixed wheel, and is configured to allow rotation of the movable wheel about the movable center; an elastic element, placed between the nut and the fixing element, and a rope configured to be accommodated in the force applicator. Additional embodiments of the fitness device are disclosed herein.
