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 protective rowing device for compression of the abdomen is provided that comprises a brace and U-shaped support member that may connect to a rowing machine seat and rail.

A system and method for analyzing and improving the performance of a body motion of an animal or human subject requires instrumenting a subject with inertial sensors, monitoring a body motion of interest, converting sensor data into motion data and animation, comparing the motion data with existing data for motion related performance parameters, providing a real-time, information rich, animation and data display of the results in color coded displays; and based on the results prescribing a training regime with exercises selected from a library of standardized exercises using standardized tools and training aids.

A weight lifting apparatus including a generally rectangular beam and two handles arranged near its ends. Each apparatus is designed to provide a more equal distribution of heavier weight across the length of the apparatus. Apparatuses may be connected to one another through locking mechanisms. A weight lifting system includes a series of weight lifting apparatuses of varying lengths and weights and is designed to gradually increase a minimum-to-maximum amount of weight. The series of apparatus gives the user a compact, functional weight increment (a gradual increase in weight for muscular strengthening), with comfortable management during the increase in weight, which is useful for a range of bodyweight motions; standing, sitting, bending, and/or on the ground. The weight lifting system also includes a base with handles and a series of additional beams that can be secured to the base to add incremental weights.

This device may be used for attaching accommodating resistance devices to a barbell, such as resistance bands or chains. The device is designed to attach to a barbell by sliding it onto the sleeve of a barbell, in the same way that weight plates slide onto the sleeves of the barbell. Once the device is installed on a barbell, the user is able to easily change resistance bands or add/subtract other weights by hanging them from a peg and/or holes in the device. The device may be used for any lift or lifts, but is especially suited to powerlifting movements such as squat, bench press, and deadlift.

An apparatus for a squat exercise comprises a user buttocks pad supported by a pivotally mounted arm for rotation in a vertical plane to allow the user to perform the exercise while in contact with the buttocks pad. The arm length and initial angular position with respect to the horizontal being adjustable. Hand grips are provided for engagement by the user during the exercise. A weight stack is operatively connected to the arm for providing a resistive force as the user squats and an assisting force as the user rises hack to the starting position. A footrest is positioned to maintain the feet of the user to allow the weight of the user to be directed through the heels during the exercise. A base supports a pivot for the arm, as well as the weight stack and footrest.

The Chair Exerciser is an apparatus and method to exercise one's core, back, and legs while working on tasks that are normally performed seated. These tasks include computer work, watching television, or computer gaming. The Chair Exerciser fits on a regular chair and one sits upon it. The Chair Exerciser's resistance can be adjusted to the suit the needs of the user. The multitasking of work and exercise is an attractive benefit to the Chair Exerciser. The Chair Exerciser can also be formed as an integral part of the chair as opposed to a portable unit.

A lower body assist device for assisting a user while performing lower body workouts is provided. The lower body assist device generally comprises handle bars, a frame, and friction reduction apparatuses. The handle bars generally comprise a shaft and support bar having handles. The frame generally comprises a main trunk and frame supports, wherein said frame supports are connected to said main trunk. The method generally entails obtaining the device, bending over and grasping the device, and moving from a starting location to a desired location. A user may also squat while grasping the device before moving from a starting location to a desired location.

An exercise device includes a first exercise bar. The first exercise bar includes a first tube extending from a first end to a second end and defining a cavity, a first weight configured to be selectively received within the first cavity, and a first slow loading mechanism coupled to the first tube proximate the second end and configured to contact the first weight when the first weight is received by the first cavity to provide a friction force to the first weight to slow the loading of the first weight into the first cavity.

A space saving and production cost saving inertia wheel training device is disclosed. In preferred embodiments the present invention comprises: a box where one or more inertia wheels are mounted horizontally; a pull belt which connects the inertia wheel with the user. The user stands with both feet on the box and can attach various accessories to the pull belt, like bars, harnesses, hip belt etc. to connect the pull belt to his body depending on the type of exercise the user wants to perform. The user adjusts the length of the belt to his body size. Then the user accelerates the inertia wheel. At the end of each movement of the user the flywheel needs to be decelerated or accelerated to allow the user to change the direction of his movement. The inertia of the wheel creates a braking force at deceleration and acceleration which leads to a training effect of the user's muscles.
