A universal foot exercise brace and ball device with new and useful characteristics for massaging and rehabilitating the plantar fascia is presented. An adjustable ankle brace surrounding the ankle naturally connects to a curvilinear tongue surface that rests over the top portion of the foot defining a passageway for a shock cord. An upper cord lock subsequently accommodates and sizes the shock cord, which in turn holds a spherical ball designed for massaging the tissues found at the bottom of the foot. Together, all the components of this utilitarian device work as one embodiment and integrated unit leaving the plantar fascia completely unobstructed to be massaged using this new device and method that securely holds a ball in place under the foot while it operates rolling under all sections of the plantar fascia as intended by the user.

A rowing machine convertible for use both indoors and outdoors. In the outdoor mode, the rowing machine is configured for adaptation to a watercraft, such as a kayak or stand up paddle board (SUP). A rower operating the rowing machine pulls on a rope or cord to cause paddles positioned at the rearward end of the machine to rotate and move the machine on a body of water. In the indoor mode, legs are attached to the machine for placement on a rigid surface. The paddles are placed in a container holding fluid.

An exercise machine includes a resistance mechanism supported on a frame; a pulley system having a first end connected to the resistance mechanism and a second end configured for movement by a user performing an exercise motion. The resistance mechanism is configured to resist operation of the pulley system during the exercise motion. A selector mechanism is operable to adjust an amount of resistance provided by the resistance mechanism to operation of the pulley system. A safety locking device automatically prevents the selector mechanism from adjusting the amount of resistance once the resistance mechanism has been engaged by the user via the pulley system.

An exercise apparatus comprises a base frame including a base frame connector. A movable frame including a movable frame connector is provided, and the movable frame connector is connected to the base frame connector such that the movable frame is rotatable relative to the base frame. An actuator is located between the base frame and the movable frame, and the actuator moves the movable frame relative to the base frame about the base frame connector so as to position the movable frame relative to the base frame in a selected position.

A piece of exercise equipment particularly for improved strength training exercises. More particularly, the invention relates to equipment that allows the user to vary tension when performing different exercises. The present invention is specifically designed for improved exercise through the variability of a tension component for use in such exercises as the plank exercise, sit-ups, push-ups and supine pull-ups that includes a core support, a guide arm, a head support, and a foot support that work in conjunction to most optimally support the user. The core support, the head support and the foot support are all connected, supported, and elevated from the floor by a central support system.

A dumbbell with a selectable number of weight disks includes a handle with pins projectable in opposing directions, a base assembly for accommodating two sets of weight disks standing upright, and having through-going openings. Neighbouring weight disks have mutually cooperating connecting arrangements which axially interconnect the weight disks but which permit radial separation. The projection lengths of the pins are stepwise selectable in order thereby to permit selection of the number of weight disks carried on the handle. The handle has, in opposing ends, connecting arrangements for interconnecting with the connecting arrangements of the innermost weight disks in the base assembly. Further, the space between the connecting arrangements of the handle is free through 360 about the handle throughout its entire length, the openings of the weight disks being centrally located.

The invention discloses a tension force stepless adjustment counterweight power generating mechanism and a fitness equipment with the same, comprising a pulling rope, a winding drum, a mounting seat, a central shaft, a spring, a generator, and a regulator; one end of the pulling rope is connected to the winding drum; a part of the pulling rope is wound on the outer peripheral wall of the winding drum; the winding drum is rotatably connected to the mounting seat; the outer end of the spring is connected to the winding drum, and the inner end thereof is connected to the mounting seat; the central shaft is rotatably arranged on the mounting seat. The mechanism organically combines the pulling force process with the power generation process, and uses a regulator to adjust the rotation damping of the generator motor shaft to adjust the pulling force in a disguised manner.

Embodiments for a multi-functional exercise system with variable resistance are provided. The system includes a base plate such as an exercise plate weight, cover plates, omnidirectional wheels, a protective skirt frame, and various attachment adapters. These are structured such that the top cover plate is attached to a top face of the base plate and a bottom cover plate is attached to a bottom face of the base plate, the omnidirectional wheels and protective skirt frame are attached to the bottom cover plate, and the attachment adapters are fastened to a central aperture defined by the base plate. The described embodiments allow a user to use this exemplary system to perform multiple exercises with various attachments.

A weight plate with a contained clamp inside a housing formed from features of the weight plate. The clamp is enclosed by the weight plate features and held in place from coming out of the housing using a fastener. Once the clamp is held, the clamp will not rotate on its own axis of rotation inside the housing. This prevents the clamp from being lost and provides easy clamping of the weight plate to a bar.

A multiple position adjustable exercise device includes a first plate, a second plate and an elastic member. The second plate is pivotally connected with the first plate. The elastic member is disposed between the first plate and the second plate, and when the second plate rotates relative to the first plate, the elastic member is twisted for providing an elastic recovering force. An initial position of the second plate relative to the first plate is adjustable for adjusting the elastic recovering force.
