A leg exerciser (30) and foot bar (20) may be included in the machine.

A portable exercise device that may be arranged in a number of different orientations and positions on the body of an individual. The portable exercise device includes a resistance assembly that enables a resistance of the portable exercise device to be adjusted.

A foldable rowing machine comprises a main part, a rowing machine seat, at least one drawing stand, and at least two turning stands. A storage chamber is formed in the main part, and a pedal is hinged to an opening of the storage chamber. A rope winder for winding a rope to a required length is disposed on main part, and a damping adjustment device for realizing a damping adjustment effect by means of magnets and a metal ring is disposed at position of a damper. A whole frame can be folded to be stored, the rope can be wound by a short distance, damping force of the damper can be freely adjusted, and a movable frame for avoiding a high-low clearance is disposed on turning stands to fulfill a shock absorption effect; and various functions are realized, and user experience of the rowing machine can be effectively improved.

Sensor data is collected from a sensor monitoring a tension generating device of an exercise machine. The sensor data is analyzed to determine whether the sensor data is within a specification. In the event the sensor data is not within a specification, an error stop mode is entered for the tension generating device.

A training device includes a backpack having a pair of shoulder straps, a rigid backbrace having at least two arms, a pair of lower support members coupled to ends of the rigid backbrace, and a resistance band coupled to each of the pair of lower support members and terminating in a handle.

A modular, portable, multi-purpose workout system is easily transported and reconfigured for different standing and seated workouts. The system at least includes a platform, a seat with a backrest, and a pair of variable resistance modules, each including an outwardly extending cable that is pulled by a user. For standing workouts, at least one of the variable resistance modules is coupled to a platform, and a user pulls up on the cable while standing on the platform. For seated exercises, at least one of the variable resistance modules is coupled to the backrest of the seat, and the cable is pulled outwardly and toward a seated user. The variable resistance modules are coupled to the platform or the backrest of the seat using elongated rigid members. The variable resistance cables may be pulled with separate handles or pulled simultaneously with a barbell component forming part of the system.

A mobile exercise device configured to enhance virtual reality experiences is provided. The system generally comprises a harness, top supports, bottom-carrying arms, resistance elements, and attachment elements secured to said resistance elements. In some preferred embodiments, a mechanical arm and/or top-carrying arm may be used to change the position of the resistance elements about a user. The resistance elements are preferably secured to a glove worn by a user, allowing for resistance in multiple directions. In one preferred embodiment, a control system may be used to adjust the tension of the resistance elements. In another embodiment, the system may be configured to operably connect to a gaming system, wherein an actuator operably connected to said resistance elements is responsible for adjusting tension based on actions by a user within a digital environment.

An exercise machine includes a cable. It further includes an interface to a moveable camera device coupled with the exercise machine. It further includes a processor configured to receive a cable-based measurement associated with an exercise performed by a user. The processor is further configured to receive, from the moveable camera device, video information associated with the exercise. The processor is further configured to provide a workout determination based at least in part on both the cable-based measurement and the video information received from the moveable camera device.
