A pilates exercise system includes an elongated frame extending from a first end to a second end, the first end and the second end both having cord attachments; a platform assembly slindingly engaged with the elongated frame, the platform assembly is configured to slide on a first track and a second track. The platform assembly includes a lower section configured to engage with the first tract and the second track, the lower section is configured to move solely along the length of the elongated frame; a middle section slidingly engaged with the lower section; and an upper section pivotally attached to the middle section. The system further includes a plurality of cords secured to both the first end of the frame and the lower section of the platform assembly and to both the second end of the frame and the lower section of the platform assembly.

The portable balancing device is formed from two modules optionally connected by a width-adjusting mechanism. The primary component of the portable balancing platform is a module. Each module may also be referred to as half of the pair of modules. Each module is formed from an upper platform and a lower platform. The upper and lower platform are separated by compressible elements that deform under a user's weight. Alternatively, a single lower platform is common across both modules, with separate upper platforms.

An exercise device and methods for using the exercise device. The exercise device is a spherical structure having a rigid surface and an opening therein for the user's hand to grasp a handle affixed in the center of the spherical structure. A series of exercises may be performed with the exercise device, including push-ups, rows and swings.

A pilates exercise system includes a pair of forward vertical members and a pair of rear vertical members extending upward from a base; a frame positioned at a top of the vertical members, the frame having one or more poles pivotally engaged with one or more framing members; the one or more poles to pivot from a horizontal to a vertical position; a platform assembly slindingly housed within the base, the platform assembly is to slide on a first track and a second track, the platform assembly, having a lower section to engage with the first track and the second track; a middle section slidingly engaged with the lower section; and an upper section pivotally attached to the middle section; and attachment elements secured to the vertical members and to provide locations for attachment of exercise equipment.

A long travel cable carrier guide has a plurality of guideposts that support an upper portion of a cable carrier. The plurality of guideposts include rollers that move between an extended and retracted position that allows the cable carrier to pass by the guideposts. The rollers automatically return to an extended position wherein the rollers protrude into the path of the cable carrier and provide support to the upper portion of the cable carrier as needed.

Disclosed herein is a skate spinner including a platform configured of a flat board having a user's foot placed thereon, and a support unit corresponding to a lower part of the platform contacting a ground surface and having a curved protruded shape configuring a curved surface starting from a front end to a rear end, wherein the support unit is configured to have a series of plates each having a thickness equal to at least a thickness of an ice-skate blade and being aligned along a left-to-right direction at a predetermined distance, wherein, when observing a cross-section of the skate spinner taken along a direction being perpendicular to a front-to-rear longitudinal direction of the skate spinner, a height of each plate becomes higher starting from the plates positioned at both side ends of the skate spinner towards the plate positioned at a center of the skate spinner, and wherein an overall bottom surface of the plates contacting the ground surface configure a spherical surface outline. As described above, the skate spinner may allow a user to embody spin movements, which correspond to the same movements performed on ice, even on generally flat ground surfaces outside of the ice, when practicing for the spin movements using the skate spinner, wherein the skate spinner includes a support unit contacting the ground surface and having an overall spherical surface outline, and may allow the user to naturally tilt sideways (i.e., from left to right, and vice versa) in accordance with a shift (or change) in a center of gravity (or weight) according to front-to-back movements of the user's body as well as a shift in the center of gravity according to left-to-right movements of the user's body.

An exercise system, in a first mode of operation, provides for strengthening of legs of a user and enhancing the user's ability to develop and maintain balance and, in a second mode of operation, for providing various forms of core, arm, and upper body training. The system includes two resilient hemispheres each having a projecting dome and, on an opposite side, a rigid substantially flat weighted base in relationship about each hemisphere and a circumferential ring is proportioned to engage a periphery of the base of each hemisphere. An outer area of the periphery of each base includes elements with connecting rings secured to the engagement elements. Resistance training bands of selectable resistance are securable to one or plural connecting rings. A push-up handle of each hemisphere is press-fittably securable into an axial recess within the weighted base and selectably connects to different weights within the recess.

A method of differentially tuning a lower limb muscle in a human in need thereof is provided. The method includes placement of at least two calibrated, differential disturbances or protuberances under the human's feet thereby tuning a lower limb muscle.
