An adjustable weight exercise system is provided. A permanent weight assembly and a plurality of interlocking weights are provided. A base comprises an interlocking weight carrier, wherein the interlocking weights are supported on the interlocking weight carrier and an interlocking weight selector, wherein the interlocking weight selector is adapted to cause interlocking weights to be set to be locked to the permanent weight assembly while the permanent weight assembly is not on the base, wherein placement of the permanent weight assembly on the base causes interlocking weights that are set to be locked to the permanent weight assembly to be locked to the permanent weight assembly, and wherein placement of the permanent weight assembly on the base does not cause interlocking weights that are not set to be locked to the permanent weight assembly to be locked to the permanent weight assembly.

An ankle exerciser device is described. The device can include a base component, a jointed foot plate assembly attached to the base component, the jointed foot plate assembly comprising a foot plate and a joint, the joint configured to allow the foot plate to tilt, pivot, and/or rotate relative to the base component, and a maze board attached to the foot plate of the jointed foot plate assembly, the maze board comprising a maze. A method of exercising the ankle can include positioning a ball in the maze of the maze board, and moving the ball through the maze by applying forces to the foot plate with a foot.

An exercise device includes a jug including a first external cutout portion and a second external cutout portion together forming an external cutout having a cross shape in the outer surface of the jug. The jug also includes a first, second, and third handle. The exercise device is configured to allow a user's wrist and forearm to enter the cutout portions.

An apparatus, kit, and method for rehabilitating and/or strengthening the soft tissues of a user's lower arm is disclosed. The apparatus has a first arm with a proximal end and a distal end; a second arm with a proximal end, a distal end, one or more discrete sections therebetween for engaging one or more weights, and a means for providing an audible feedback to the user upon completion of an exercise repetition or a half-repetition; and a hinge in contact with the proximal ends of the first and second arms. The hinge is configured to adjust the distance between the distal ends of the first and second arms, or the angle separating the first and second arms.

Controlling an exercise machine includes receiving a stream of measurements of extension of a component of an exercise machine. It further includes characterizing the stream of measurements including detecting at least one extremum having at least one extremum parameter. It further includes matching the extremum parameter with a previously determined signature associated with a user. It further includes changing an output of the exercise machine based at least in part on the match.

Controlling an exercise machine includes receiving a stream of measurements of extension of a component of an exercise machine. It further includes detecting a first phase of a repeated motion. It further includes detecting a transition to a second phase of the repeated motion. A time constraint is applied to the detection of the transition to the second phase of the repeated motion. It further includes controlling a resistance associated with the second phase of the repeated motion.

A fitness slider is provided that is capable of holding a weight plate during use, to be manipulated by one or more extremities using the weight plate as the engagement surface for the user's hand or foot. Another fitness slider is configured to mate with different sizes of weight plates. Yet another fitness slider is provided that includes a handle on top of the weight plate as the engagement surface.

A hand weight includes a chassis including a handle portion configured to be grasped by a user such that a forearm of the user extends along an axis, and a flexible element attached to the chassis. The hand weight can be configured to receive a movable mass, and the flexible element can be configured to at least partially support the movable mass such that the movable mass forms at least part of a sprung mass of a hand weight assembly including the hand weight and the movable mass, the sprung mass configured to move relative to the chassis of the hand weight and deform the flexible element in response to a force in a direction along the axis applied to the handle portion by the user while grasping the handle portion.

An article of manufacture providing an exercise device for work-out with a stroller according to the present invention includes the stroller having a frame having a front portion and a rear portion, a front wheel assembly coupled to the front portion of the frame, a pair of rear wheels coupled to the rear portion of the frame and a handle coupled to the rear portion of the frame above the pair of rear wheels and a plurality of barbells coupled across the stroller for supporting removable weights on both ends of the barbells. A first barbell coupled across the rear portion of the frame between the pair of rear wheels and the handle. A second barbell coupled across front wheel assembly. A third barbell coupled across the handle.

Embodiments herein are directed to an aquatic exercising assembly. The aquatic exercising assembly includes a container having a liquid retention portion. The liquid retention portion includes a bottom wall, a pair of opposing sidewalls, and a pair of opposing end walls, a pedal assembly and a paddle assembly. The pedal assembly is rotatably coupled to the one of the pair of opposing end walls. The paddle assembly is coupled to each one of the pair of opposing sidewalls. The paddle assembly is movable between a rearward position and a forward position in a longitudinal direction. The pedal assembly is rotatably moved by a lower body movement of a user and the paddle assembly is moved by an upper body movement of the user.
