Balance training aids are disclosed. Example embodiments disclose a user placing all or part of their body weight on a top surface of a platform that is sitting atop an unstable base member and attempts to balance or complete a balance challenge. In example embodiments, the user places at least a portion of one foot atop the platform during the balance challenge. Adjustability features can be provided so as to provide a varying degree of adjustability to the unstable base member, and thus, provide a varying degree of balance challenges or levels of difficulty.

An ankle box system includes at least one ankle box and a riser. Each of the ankle boxes has an upper surface and a lower surface, and a plurality of projections extending from the lower surface, such as at the ends thereof. The riser has a bottom surface and a plurality of riser levels, each of the riser levels configured for selectively receiving one of the projections of at least one of the ends of an ankle box, at least two of the riser levels having an upper surface being disposed at different elevations from a bottom surface of the riser. The upper surfaces of the ankle boxes have a shape configured to enhance exercising the human ankle.

A multipurpose fitness block suitable for a variety of upper body and lower body exercises is presented. The multipurpose fitness block contains a block body, a plurality of weight inserts, a carrying handle, and a plurality of attachment elements. The block body contains a plurality of handling channels and a plurality of weight holders. The plurality of weight holders is distributed about the block body. The plurality of handling channels is distributed about the block body. The plurality of weight inserts is connected along the plurality of weight holders. The carrying handle is connected adjacent to the block body. The plurality of attachment elements is distributed about the block body.

A multi-mode athleticism movement measurement system includes an athlete-borne acceleration sensor and an athleticism processing device to determine athleticism information based upon one or more timing measurements from the athlete-borne acceleration sensor, the athleticism information corresponding to any of multiple athleticism measurement modes available on athleticism processing device and selectable by a user. A data link between the athlete-borne acceleration sensor and the athleticism rating processing device transmits the one or more timing measurements from the athlete-borne acceleration sensor to the athleticism rating processing device.

An exercise step and method of exercising a user's legs is disclosed. The exercise step includes a main body which has a substantially planar and horizontally oriented upper wall and a sloped wall extending from bottommost surface of the exercise step to the upper wall. In use, a user steps on the sloped wall with a heel portion of his or her foot and raises the heel portion such that a sole portion of his or her foot is supported by the upper wall.

A slant board device, formed of a base on the ground, and supporting a slanted top surface. The top surface has a pad and artificial grass. The top surface is used as a slant board for exercizing with cleats on.

An exercise step, usable for any of a variety of step exercises, can include a solid top surface that may be polygonal in shape. At least a portion of an underside of the exercise step can be formed in a honeycomb configuration, thereby reducing weight of the step as well as the material required to make the step. Handles may be formed by indentations in sides of the step for ease of lifting and positioning. The handles may be formed in opposites of the polygonal shape. In some embodiments, the polygonal shape may be symmetrical or may include longer and shorter sides in an alternating arrangement. At least a portion of the bottom of the step can be formed from an anti-slip material.

A fitness training apparatus comprising a controller configured to communicate instructions to a load generator to apply a selectively adjustable load to at least one retractable line provided in or on a base, the retractable line having a free end region, the at least one retractable line being extendible from a retracted state to an extended state upon application of a force to the free end region, wherein the load applied to the at least one retractable line acts against the force applied to the free end region. The controller is configured to perform operations comprising setting a target speed band for the at least one retractable line, receiving a speed of the at least one retractable line, and responsive to comparing the speed to the target speed band, modifying the selectively adjustable load to the at least one retractable line to maintain the target speed band.

An ankle box system includes at least one ankle box and a riser. Each of the ankle boxes has an upper surface and a lower surface, and a plurality of projections extending from the lower surface, such as at the ends thereof. The riser has a bottom surface and a plurality of riser levels, each of the riser levels configured for selectively receiving one of the projections of at least one of the ends of an ankle box, at least two of the riser levels having an upper surface being disposed at different elevations from a bottom surface of the riser. The upper surfaces of the ankle boxes have a shape configured to enhance exercising the human ankle.

A physical therapy system including a boot assembly, a track assembly and a communications assembly is disclosed. The boot assembly includes a boot that is worn on the foot of the user with the knee that requires treatment. The boot includes a cushioned sole provided by a sponge within the boot. The sponge being entirely enclosed by a cover. The track assembly includes a track on which the boot is maneuvered on. The boot and the track having a low friction coefficient to allow the boot to easily slid on the track. The user may maneuver the boot in a manner that rehabilitates their knee. Within the boot is the communication assembly which includes a processor and sensors to gather data from the usage of the boot. The collected data is communicated to a mobile device allowing a user to track their therapy sessions and progress.
