Some embodiments include an outer tube, a pivot structure, an inner tube, a rotational element, and a central rod. The pivot structure perpendicularly intersects the outer tube at a midpoint of the outer tube. The inner tube is coaxially within the outer tube. A first portion of the inner tube is within the outer tube on one side of the pivot structure. A second portion of the inner tube is within the outer tube on another side of the pivot structure. The rotational element couples to the pivot structure, rotates about an axis of the pivot structure, and interfaces with the first and second portions of the inner tube to cause rotation of one portion of the inner tube in a first rotational direction to counter-rotate the other portion of the inner tube in a second rotational direction. The central rod is within the inner tube and translates axially.

A treadmill may include two separate left and right belts rotating around two sets of rollers, four legs having an adjustable height via air suspension to customize an inclination of the treadmill, a thermoelectric assembly, a fragrance assembly having a rotating fragrance cartridge to emit various smells toward a user of the treadmill, a display on which exercise programs are played, and an attachment module having a dispensing tray on which treats are dispensed. A handle of the treadmill may have a sensor to sense a height and front-rear position, and a belt divider provided between the left and right belts may have position or proximity sensors to sense a left-right position. An inclination of the treadmill may be automatically adjusted according to positions detected by the sensors, and the fragrance assembly, attachment module, and inclination may be automatically operated in accordance with an exercise program played on the display.

A balance training system including a riding plate; a load distribution sensor; a load sensor; a mobile body on which the riding plate, the load distribution sensor, and the load sensor are disposed; and a control unit configured to calculate a reference position based on positions of feet of a trainee detected by the load distribution sensor, then calculate a center of gravity position of the trainee based on the load detected by the load sensor, and control a movement of the mobile body based on a change of the center of gravity position with respect to the reference position. The control unit is configured to update the reference position based on the changed positions of the feet of the trainee when the change of the position of at least one of the feet of the trainee is detected by the load distribution sensor.

A method controls a piece of exercise equipment when a user of the exercise equipment is using a virtual reality headset. The method begins by receiving sensor inputs detecting a position of the user with respect to the exercise equipment. An operational zone of the exercise equipment is then determined. It is then identified when the user is moving toward a warning area within the operational zone of the exercise equipment. The method then sends signals to the virtual reality headset. Based on the signals, the virtual reality headset creates audible and visual outputs to instruct the user to move back fully into the operational zone of the exercise equipment.

Methods and systems for calibrating a level of intensity of a fitness exercise given a target effort value facilitate optimal exertion for an individual performing the fitness exercise. An instantaneous effort value is determined based on measured real-time and historical data and communicated to the individual. An aspect of the fitness exercise is adjusted based on a difference between the instantaneous effort value and a target effort value.

An exercise machine inclination device for providing variable exercise intensity on an exercise machine by inclining the exercise machine. The exercise machine inclination device generally includes a base adapted for being positioned upon a floor, a support structure adapted for supporting the exercise machine, a hinge pivotally connecting the base and the support structure and an actuator connected between the base and the support structure, wherein the actuator adjusts an angle of the support structure.

An exercise device comprising a metallic box, two motors mounted at left and right sides of the box, a mirror touch screen, a camera, a loudspeaker, two motors mounted at the left and right bottom of the box, movable arms at slide tracks at both sides, a voltage transformer for the mirror touch screen, and four drive boards for four motors. All these four motors connect with gear reducers. Four carriages ride on both sides of slide tracks. The upper left and right two carriages provide support for upper limbs exercise. The lower left and right two carriages provide support for lower limbs exercise.

Systems and methods for assisting a user with creating a custom shots-made basketball practice arrangement are provided. A detector detects made basketball shots. A user interface receives a user selection of a subset of pass receipt locations for a custom shots-made basketball practice arrangement located about a basketball playing surface. A control system receives data indicating the user selection and a number of shots to be made and commands an ejector to launch basketballs to a particular one of the pass receipt locations in the subset until data is received indicating that the selected number of shots to be made are made at the particular one of said plurality of pass receipt locations, cease launching the basketballs to the particular one of the pass receipt locations, and begins launching basketballs to a second particular one of the pass receipt locations in said subset.

The described embodiments relate to systems, methods, and apparatuses for providing linear tension to multiple areas of a person to improve training and exercise. The tension can be applied by cables supplied from cable spools that are attached within a resistance assembly. The resistance assembly can be worn as a backpack during exercises, thereby providing a portable means through which tension can be provided to the body. The cables from the resistance assembly can be attached to appendages such as the wrists and legs of the person, and the tension provided by the cables can be adjustable. For instance, the tension can be made non-uniform across the body in order to improve the person's ability to maneuver in situations where there is an imbalance of force on the body.
