An exercise machine including a motor assembly that provides both motor driven resistance forces and motor driven rotation forces. A frame of the machine assists a user in the performance of an exercise, and separates a treadmill portion of the machine from a weightlifting portion of the machine. The treadmill portion is driven by the motor driven rotation forces, and the weightlifting portion is driven by the motor driven resistance forces, thereby providing a universal machine that provides for performance of a plurality of exercises.

Holistic training device wherein a trainee user executes a training operation of sequential cycles of a first step of synchronized contraction of left limbs and extension of right limbs, followed by a second step of reverse synchronized contraction of right limbs and extension of left limbs thereof, including a frame (10) with shorter parallel beams (1,2), longer parallel beams (3,4) and a beam (5) extending intermedially in between beams (1,2) with plate extensions (31,41) receiving freely rotatable axles (53,54) at the sides thereof. Pulleys (56a,57a-56b,57b) are fixedly mounted at the ends of the axles (53,54) and pulleys (16a, 17a-16b, 17b) are mounted proximally to the ends of beams (1,2) with straps (36a,36b-37a,37b) freely rotatabler around these pulleys, rails (33,34-43,44) being adapted to receive platforms (60) sliding thereupon, these platforms being activated through handgrip items (35a, 45a) gripped by the palms and foot hold items (35b, 45b) nesting the soles of the trainee user to implement the aforementioned sequential exercising cycles.

An exercise system includes two or more exercise machines coupled together. Each exercise machine can include a modular exercise machine offering one or more unique exercise functions. To vary or change the exercise system, the exercise machines may decouple from each other and couple to a different exercise machine. Examples of the exercise machines include osteogenic, muscular hypertrophy and cardiovascular devices. These exercise systems enable modifications to the exercise machines for user rehabilitation. The exercise machines can monitor other exercise machines and provide feedback to a user through a computer display.

An ambulation simulating apparatus, including: a user feet interface comprising foot rests; a dynamic inertia mechanism configured to provide an inertial load when a downwardly force is applied due to the foot and a kinematic connection configured to enable transmission of motion from the feet interface to the dynamic inertia and backwards as the dynamic inertia mechanism resists said downwardly applied force by the foot.

An exercise system may include a dip apparatus having gripping bars for a user to grip and one or more resistance bands releasably attachable to the dip apparatus below the gripping bars to assist the user when performing a dip exercise by providing an upward force counteracting at least a portion of the user's weight. To this end, the dip apparatus may include support bars disposed below the gripping bars, where the support bars are structurally configured to engage with one or more resistance bands. More particularly, each of the support bars may include couplers that have a portion structurally configured to receive a resistance band, which may be formed as a continuous loop.

A sliding clip is disclosed. The clip may slide along a strap, for example on a belt. Optionally the clip includes a fastener. Optionally, the fastener may be configured to hold one or more cords, for example bungee cords. For example, the cords may fit into a channel and/or be immobilized by a pressing them with a clamp and/or a threaded knob. Optionally the positions of the cords may be adjusted and/or the fastener may be opened for replacement of the cords. Optionally the fastener is configured for one handed use. For example the parts may be retained together even when the fastener is opened. Optionally one or more clips and/or bungee cords are mounted of a belt assembly forming an exercise device.

A method is disclosed for using an artificial intelligence engine to modify resistance of pedals of an exercise device. The method includes generating, by the artificial intelligence engine, a machine learning model trained to receive measurements as input, and outputting, based on the measurements, a control instruction that causes the exercise device to modify, independently from each other, the resistance of the pedals. While a user performs an exercise using the exercise device, the method includes receiving the measurements from sensors associated with the pedals. The method includes determining, based on the measurements, a quantifiable or qualitative modification to the resistance provided by a pedal of the pedals. The resistance provided by another pedal of the pedals is not modified. The method includes transmitting the control instruction to the exercise device to cause the resistance provided by the pedal to be modified.

A walking assist device has a frame, fixed handles, rails provided with movable handles, front wheels, rear wheels and that serve as drive wheels, drive units, a battery, and a drive control unit, and travels forward or rearward together with a user that walks while grasping the fixed handles or the movable handles. The walking assist device has an operation mode switching unit that switches between a training mode, in which a load is applied to operation of the body of the user performed as the user walks, and an assist mode in which a load on operation of the body of the user performed as the user walks is alleviated.
