Methods, systems, and apparatus, including computer programs encoded on computer storage media, coordinate dynamic adjustments of a trailer based in part on a user profile associated with a user physically present at the trailer and an activity profile associated with an activity selected to be performed at the trailer. A dynamic adjustment may modify a tilt of a lower surface of the trailer. A dynamic adjustment may modify a dimension(s) of the trailer based in part on a detected object(s). Various dynamic adjustments may occur concurrently, individually and/or sequentially. The trailer may be a moveable trailer for temporary attachment with a vehicle.

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.

A motorized lifting rack that selectively lifts and lowers a barbell through linear actuators is provided. The powered lifting rack can engage a barbell at floor level. The linear actuators can also selectively raise and lower safety bars design to “spot” the barbell for a single user. The powered lifting rack is embodied in a system that includes a platform that the safety bars can nest in. The platform provides a plurality of actuating benches for a user of the barbell to utilize.

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.

In one aspect, a method useful for automating, personalizing, and optimizing a resistance force in an exercise across time and space, the system including the step of providing an exercise machine. The method includes the step of providing a biometric sensor coupled with a user performing an exercise on the exercise machine. The method includes the step of obtaining a user's profile data, wherein the user's profile data comprises factors such as a user's history of exercising on the exercise machine. The method includes the step of obtaining a user input into an exercise resistance controller of the exercise machine. The method includes the step of, while the user performs one or more repetitions of the exercise on the exercise machine, obtaining real-time data of a set of parameters of the one or more repetitions of the exercise on the exercise machine. The method includes the step of obtaining a user's biometric data.

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 system for rehabilitation is disclosed. The system for rehabilitation includes one or more electronic devices comprising one or more memory devices storing instructions, one or more network interface cards, and one or more sensors, wherein the one or more electronic devices are coupled to a user. The system for rehabilitation further includes one or more processing devices operatively coupled to the one or more memory devices, the one or more network interface cards, and the one or more sensors. The one or more processing devices are configured to execute the instructions to receive information from the one or more sensors. The one or more processing devices are further configured to execute the instructions to transmit the information to a computing device controlling an electromechanical device, via the one or more network interface cards.
