A variable-resistance exercise machine with network communication for smart device control and interactive software applications, comprising a network interface that receives input from a user device and provides output to a user device; a plurality of moving surfaces that each provide an independent degree of resistance to movement based on received input, a sensor that detects movement and provides output to a user device based on the movement.

A device for visual walking includes an omnidirectional exercise machine and foot wearable devices. A method for visual walking is applied to the device for visual walking. When a user wears the omnidirectional exercise machine and uses the loading frame to adjust a height of the omnidirectional exercise machine, and wears the foot wearable devices to stand and run on a running plate, human body posture data is obtained by tracking a human body torso. Then displacement data of left and right feet is obtained by tracking the feet. A virtual position and a movement speed of the feet are respectively obtained according to the displacement data, the leg posture is inferred by the IK algorithm according to the virtual position and the walking action of the virtual character is controlled according to the human body posture data, the movement speed of the feet, and the leg posture.

An exercise apparatus orienting foot pedals and handlebars having first and second rotating armatures for generating subtended paths of rotation, with motors to revolve the first and second rotating armatures in opposite directions and allowing the subtended paths to migrate from a first two-dimensional plane into a second two dimensional plane and back into the first two-dimensional plane.

Systems and methods for fitness tracking are provided. An exercise apparatus is in networked communication with a fitness tracking computing system. The configuration and location of movable components of the exercise apparatus is determined based on sensors. This information is provided to the fitness tracking computing system via networked communication.

Systems and methods for fitness tracking are provided. A fitness tracking computing system conveys information over a network to a visual display of a device viewable by a user. The device can be a smart phone, tablet computer, or a laptop. Instructions are conveyed to the visual display that identify an exercise to be performed by the user. during performance of the exercise by the user, an exercise status summary is provided to the visual display. Based on the user's movements during performance of the exercise, as tracked by a camera, feedback is provided to the visual display.
