Disclosed are example embodiments of systems and methods for exercise including an exercise machine including a multiple directional force component configured to apply a multiple directional force to an exercise machine-human body interface, the multiple directional force component further configured to provide a divergent intensity to the exercise machine-human body interface to provide the human body with a resistance during a physical exercise and an artificial intelligence (AI) component configured to control the multiple directional force component. In an example, the AI component may control the multiple directional force component based on morphological characteristics and variability of running speed parameters including at least one of stride length, stride frequency, explosive drive force, and arm drive.

An exercise machine using motion sensor to track exercise, comprising: an exercise equipment, including a mainframe, the mainframe is fixed and won't be moved by user's movement, an operating mechanism, the operating mechanism is arranged on the mainframe and it will follow the movement of the user; wherein the operating mechanism having a motion sensor, inside the motion sensor having a multiple-axis tracking sensor module and a first microprocessor for detecting the height displacement of the operating mechanism and transmitting the height displacement signal to an electronic control device, then processing by a second microprocessor arranged inside the electronic control device to know whether the motion track of the user reach the preset position during exercise to ensure the effect of exercising.

According to one example, an exercise system includes a vertical housing, a first weighted touchpoint coupled to the vertical housing and configured to allow a user to exercise one or more muscles on a first side of the user, a first weight system coupled to the first weighted touchpoint, a second weighted touchpoint coupled to the vertical housing and configured to allow the user to exercise one or more muscles on a second side of the user, and a second weight system coupled to the second weighted touchpoint. The exercise system further includes a control system configured to cause the first weight system to automatically provide a first heavier weight to the first weighted touchpoint for a first exercise and further cause the second weight system to automatically provide a second lighter weight to the second weighted touchpoint for the first exercise.

A locking and release mechanism for simultaneously positioning an exercise arm in two perpendicular directions, having: (a) a first positioning guide for positioning an exercise arm in a first direction; (b) a second positioning guide for positioning the exercise arm in a second direction; and (c) a locking and release mechanism for locking and releasing the first and second positioning guides, wherein the locking and release mechanism includes: a moveable tab, and one or more positioning pins, wherein movement of the moveable tab locks one two positioning pins into apertures in each of the first and second positioning guides.

Computing device enhanced training environment system comprising a computing device, I/O subsystem for permitting a user to enter at least one attribute of the training or of the trainee, a plurality of sensors for generating sensory information, a training environment in which a training activity takes place, a database containing training related information. The computing device enhanced training environment system configured for at least one of the following: design a training program for a plurality of users, monitor training program performance, monitor training performance, instruct a user about the training, determine and/or set difficulty level in training apparatus.

A weight system having at least one weight stack moveable in a vertical direction on a lift rod, and a bearing block for housing a linear bearing. The invention further includes a method and apparatus for aligning the linear bearing.

A calf exerciser includes a free standing platform with independent foot braces that pivot and rotate for providing an optimally positioned foot and ankle position for a calf exercise. A pair of rotating platforms mount to a base, and each rotating platform has a pivot brace that angles left and right. Positioning and locking the foot braces at various positions of rotation and right/left angles provide a selectable, varied position as the calf exercises generally involve an ankle driven force against the foot braces, often bearing on the ball or arch of the foot. A beveled or curved edge with a grip surface further enhances contact with the user's foot.

A method and system for measuring exercise data using a plurality of wireless sensors is disclosed. The plurality of wireless sensors are attached onto or into a plurality of pieces of strength training equipment, wherein each individual wireless sensor from the plurality of wireless sensors is attached to and associated with an individual piece of strength training equipment of the plurality of pieces of strength training equipment. An individual piece of strength training equipment of the plurality of pieces of strength training equipment is selected and the wireless sensor is registered with selected piece of strength training equipment with a computing device. Strength training equipment details may be identified through the computing device.

The present disclosure relates to a grip apparatus for exercise equipment, the grip apparatus comprising: a first annular member having a first annular sidewall and a first flange extending radially inwardly from the first annular sidewall; a second annular member having a second annular sidewall and a second flange extending radially .[.inwardly.]. .Iadd.outwardly .Iaddend.from the second annular sidewall, a diameter of the second annular sidewall being less than a diameter of the first annular sidewall, the second annular member being positioned within the first annular member whereby the first annular sidewall, the second annular sidewall, the first flange and the second flange define together an annular chamber; a handle member connected to the second annular sidewall; and a bearing in the annular chamber, the first annular sidewall frictionally engaging a first race of the bearing and the second annular sidewall frictionally engaging a second race of the bearing.

A combination exercise assembly for performing aerobic and strength training exercises includes a base, which can be positioned on a substantially horizontal surface. A stationary bicycle is engaged to the base so that a user positioned on a seat of the stationary bicycle faces a first end of the base. A lat pulldown machine engaged to the base proximate to a second end of the base is positioned for engagement by the user positioned on the seat of the stationary bicycle. The stationary bicycle is pedaled to perform aerobic exercise and the lat pulldown machine resists a pulldown motion to perform strength training exercises.
