In various embodiments, an exercise device is provided. The exercise device may comprise a mat and a plurality of indicators. The mat may have a top surface. The plurality of indicators may be disposed on the mat (e.g., on the top surface). In various embodiments, an exercise device is provided. The exercise device may comprise elastomeric base member and a plurality of indicators. The plurality of indicators may be disposed on the elastomeric base member. Moreover, the plurality of indicators may be recognizable by a user in response to receiving an instruction to perform a movement.

An exercise apparatus includes a frame body, two driving levers, two pedals, a linking device and at least one resistance device. The driving levers are pivotally connected to two side frames of the frame body, respectively. The pedals are connected to the two driving levers, respectively. The linking device is connected the driving levers so as to lead the driving levers to be swung reciprocally and simultaneously. The resistance device is driven by one of the driving levers so as to generate a magnetic resistance.

A method for recommending golf-related contents is provided. The method includes detecting at least one body part of a user from a captured image by using an artificial neural network model, when the captured image related to the golf swing of the user is acquired; estimating at least one problem about the golf swing of the user by referring to the position of the detected at least one body part; and deriving, in reference to information related to the problem associated with the golf-related contents, at least one piece of candidate content associated with the at least one problem from among golf-related contents.

An information processing device includes a controller. The controller is configured to acquire an estimated value of a posture angle of at least any one of multiple body parts of a user based on sensor data representing movement of at least some of the body parts of the user and a trained model. The trained model is trained and outputs the estimated value of the posture angle when input with the sensor data.

A retractable wall mounted exercise rack system for providing an exercise rack that may be easily and compactly stored when not in use. The retractable wall mounted exercise rack system generally includes one or more brackets attached to a wall, a pair of support members, and a plurality of arms pivotally extending from the brackets and pivotally connecting to the support members. One or more actuators are connected between the brackets and the arms to assist in lifting the structure into a compact retracted position for storage.

A variable weight toning strap having a flexible member and a plurality of generally rectangular sections, wherein each of the plurality of generally rectangular sections are disposed transversely along the flexible member length, include a top surface at least partially defining an upper surface of the flexible member, at least one perpendicular sidewall extending in a direction substantially perpendicular to the top surface, and a section width separating a rear face and a front face of the sections. Two of the sections have a discontinuous upper slit defined by the at least one perpendicular sidewall of each of said sections flanking the upper slit, wherein the upper slit spans the section width and terminates into a valley. The sections also each define a channel with a selectively removably and frictionally retained weight disposed therein.
