A low friction rehabilitation board having an integral band retaining feature is described. The rehabilitation board may have a coefficient of static friction of no more than about 0.5 and in some embodiments no more than about 0.06. The rehabilitation board has a plurality of band retaining feature configured along one or both ends and may be an integral band retaining features being formed in the board. Additionally, the rehabilitation may include one or more band retaining features on one or both sides of the board. The unique configuration of the band retaining features enables rehabilitation method heretofore not possible with a single board. Resistance bands may be retained in the band retaining features and coupled to a user's limb, such as a foot or ankle, to resist motion, such as sliding or extending the foot along the low friction surface of the rehabilitation board.

A training device that is easily and temporarily attachable to any existing sled training device. The training device includes a flexible, elongated plank that resides between an athlete's legs and helps train the athlete to maintain a proper stance width while blocking or pushing a sled. An embodiment includes a magnet secured to the plank at a first end of the plank. The magnet engages the sled and is detached from the sled when the athlete pushes the sled with an improperly narrow stance width. As a result, the athlete experiences a tactile and visual aid to distinguish between proper and improper stance width while pushing a sled.

Systems and methods for tracking user movement during physical fitness activities are presented. A camera tracks movements of objects of interest in a field of view thereof during an exercise routine to log, instruct and provide feedback data to assist the user in reaching fitness goals. The user can also share his data with friends or teammates, for example through social media or in a client-server environment.

A vertically adjustable double end bag system includes a double end bag connected to a tether. The tether may be a continuous cord o two connected cords, and may be flexible or substantially fixed length. The double end bag includes an adjuster mechanism for selectively positioning the bag. A support, such as may be connected to a door or other upright fixture or as may be free-standing via a base, connects to and suspends the tether.

Systems, devices, and methods are described for providing, among other things, a neck and spine strengthening device. In an embodiment, the neck strengthening device includes a spinal resistance assembly including at least one resistance component configured to apply a resist force or to resist rotation about a first axis. In an embodiment, the spinal resistance assembly permits lateral neck rotation of a user about the first axis while substantially limiting flexional and extensional movement. In an embodiment, the neck strengthening device includes a device securing assembly configured to physically anchor the device to an anchoring structure. In an embodiment, the neck strengthening device includes a head affixing assembly configured to secure to a head of a user during use. In an embodiment, the strengthening device is instrumented with sensors and an embedded computing system to securely exchange exercise performance and configuration data with local client devices and monitor and record exercise activity and exercise performance data to remote, internet connected serves.

Innovative apparatuses and methods for a novel training device is provided that includes a base, a frame, a material attached to the frame, wherein the material comprises a non-solid material; and an image affixed to a first side of the non-solid material, wherein the image is viewable on the first side of the non-solid material and viewable on a second side of the non-solid material.

An aquatic exercise system includes a pool and an aquatic exercise apparatus positioned in the pool. The aquatic exercise apparatus includes a base and an aquatic exercise pole having a first substantially straight section, a second substantially straight section, and a curved transition section between the first substantially straight section and the second substantially straight section. The curved transition section includes a bend, and the aquatic exercise apparatus is positioned in the pool such that bend is above a surface of water in the pool.

A fitness assembly for performing various exercises that is securably mountable to a mounting surface using one or more vacuum devices. In one embodiment, a vacuum-mounted fitness assembly comprises a base element and at least one vacuum device removably coupled to the base element. In one embodiment, the base element has an elongated shape and is removably coupled to two vacuum devices. In another embodiment, the base element has a circular or non-elongated shape and is removably coupled to one vacuum device. The base element includes a plurality of apertures and/or slits to which one or more bands and/or straps may be attached. In one embodiment, the fitness assembly also includes one or more accessories that enable the fitness assembly to be used to perform exercises such as boxing, squats, rowing, bicep curls, and others.
