An exercise machine adjustable resistance system and method for efficiently varying the workout resistance for an exercise machine. The exercise machine generally includes a carriage movably positioned with respect to the at least one rail, a plurality of springs selectively connectable to the carriage to provide a resistance level to the carriage, a plurality of electrically actuated mechanical devices adapted to latch a corresponding one of the plurality of springs to the carriage when in the latch state and unlatch a corresponding one of the plurality of springs to the carriage when in the unlatch state and a control unit in communication with the plurality of electrically actuated mechanical devices to selectively control the state of each of the plurality of electrically actuated mechanical devices to be within the latch state or the unlatch state.

An interactive exercise system includes a mechanical support system and a display module held by the mechanical support system. A mirror element is attached to at least partially cover the display module. At least one movable arm is connected to the support system and at least one force-controlled component is connected to the mechanical support system. The force-controlled component can be graspable by a user and allows for a range of exercise types and programs.

Tracking information is provided from one or more mobile communications devices indicating fitness activity recorded on personal fitness devices of multiple users over a predetermined baseline period of time. A mobile communications device of a challenging user communicates a fitness challenge that is to occur over a predetermined challenge period of time to one or more challenged users. Leveled challenged fitness metrics of the challenging user and of the challenged user is computed based on fitness activity of the challenging user and the challenged user that occurs during the challenge period of time and during the baseline period of time. The leveled challenged fitness metrics are communicated to the mobile communication devices upon completion of the challenge period of time to indicate a winner of the challenge.

The present disclosure provides a system that quantitatively tracks an individual's diet and exercise using smart devices (phones, watches, and other wearables). Unlike existing programs, which work in energy units (calories), the present system works in mass units (grams) and satisfies the fundamental physics law of conservation of mass. Food ingested is tracked as well as exercise in order to place the user on a quantitative, custom diet that safely and effectively results in weight loss. In addition to rigorously treating the problem of weight loss by addressing the physics that underlies diet and exercise, the system empirically learns about the user over time such that performance may be optimized.

Aspects of the present disclosure provide methods, apparatuses, and systems for dynamic starting rates for guided breathing. According to an aspect, a user's initial breathing metric is determined. A multiplier is then determined, where the multiplier varies as a function of the initial breathing metric within a range. The level of intensity of the multiplier may vary, and may be a dynamic feature based on the determination of the user's initial breathing metric. Once the multiplier is determined, the multiplier is applied to the user's initial breathing metric to determine a starting breathing metric for guided breathing. The starting breathing metric is slower than or equal to the user's initial breathing metric.

A system and method for controlling an exercise device are provided herein. The system includes a memory having computer-executable instructions and at least one processor to execute the computer-executable instructions to wirelessly connect the exercise device, receive a training mode, receive at least one variable for determining a power set point, determine the power set point responsive to the training mode and the at least one variable and control a magnetic brake assembly in the exercise device responsive to the power set point.

Provided is an exercise load control device including: a patient information input unit configured to input patient information which indicates whether a patient using an exercise therapy apparatus is an atrial fibrillation patient; a heart rate information acquisition unit configured to acquire heart rate information which indicates a heart rate of the patient using the exercise therapy apparatus; and a load control unit configured to control a magnitude of a load to be applied by the exercise therapy apparatus to the patient, based on the patient information input by the patient information input unit and the heart rate information acquired by the heart rate information acquisition unit.

Described herein are systems and methods for favorably coordinating a timing relationship between a musculoskeletal activity cycle and a cardiac cycle of a user. A method may include repetitively detecting a signal that correlates to a blood volume in the user; determining an actual value of the signal that varies with the timing relationship; computing a trend of the actual value of the signal; and adjusting the movement guidance based on the trend of the actual value. A system may include a prompt device configured to provide recurrently a movement guidance to the user for guiding performance of the rhythmic musculoskeletal activity; a sensor configured to provide a signal that correlates to a blood volume in the user; and a processor configured to determine an actual value of the signal that varies with the timing relationship and to adjust the movement guidance based on the trend of the actual value.

A training device for strength training is capable of performing through use of a barbell, the training device including: a frame body; a support body configured to support the barbell from below; moving means for moving the support body to ascend and descend along the frame body; control means for controlling the moving means; and state detecting means for detecting a state of the barbell or a user, wherein the control means is configured to control the moving means based on a detection signal detected by the state detecting means. With the training device, various kinds of free-weight training can be solely and safely performed.

Stationary exercise machine. In one aspect of the disclosure, a stationary exercise machine may include one or more moveable members configured to be moved by a user, an actuator configured to selectively adjust the speed of, or the amount of resistance on, the one or more moveable members, and one or more processors. The one or more processors may be configured to receive a video, execute the video set to a first difficulty level, receive a second difficulty level, and execute the video reset to the second difficulty level.
