A modular and dynamic force apparatus for adjusting standard and dynamic torque-to-linear forces during physical activity in real-time, the apparatus including a force module, a user device and an apparatus tracking processing unit. The force module includes an open hub attachment point, wherein the open hub attaches the apparatus to an external source, one or more sensors measuring data for physical activity efficiency, an internal processor, wireless radio and force sensor module, a variable length cable, a force generating component, and motor controls. The internal processor, wireless radio and force sensor module includes an apparatus tracking measurement unit (“ATMU”) adapted to measure data, a first electronic communications channel for transmitting the measured data to an apparatus tracking processing unit (“ATPU”), and a second electronic communications channel for transmitting one or more apparatus conditions data to adjust dynamic forces. The user device receives one or more apparatus conditions data over the second electronic communications channel for real-time notification and/or adjustments to the user. The user interface includes a display that provides feedback and an apparatus tracking processing unit (“ATPU”). The ATPU includes the first electronic communications channel for receiving the measured data from the ATMU, a microprocessor, a memory storage area, a database stored in the memory storage area, and a tracking processing module located in the memory storage are. The database stores a first set of evaluation rules and a second set of evaluation rules, the first set of evaluation rules corresponding to one or more tracking parameters, and the second set of evaluation rules corresponding to the one or more apparatus conditions. The tracking processing includes program instructions that, when executed by the microprocessor, causes the microprocessor to determine the one or more tracking parameters using the measured data and the first set of evaluation rules, and determine the one or more apparatus conditions data using the one or more tracking parameters and the second set of evaluation rules.

A balance board system, comprising, a rotatable roller, a balance board having a lower surface that sits atop the rotatable roller and reciprocally rides on the rotatable roller, the balance board lower surface having a plurality of attachment points, a plurality of board connectors disposed at the plurality of attachment points, a plurality of stop connectors and a plurality of roller stops coupled to at least two of the plurality of stop connectors, the plurality of roller stops are attachable to the balance board at a respective one of the plurality of attachment points.

Exemplary arrangements provide leg training devices suitable for high intensity training of hip flexors while simultaneously training the extensors of hip and knee joints. The exemplary leg training devices include foot fixings which are permanent vertically movable components of the device, each of which are configured to releasably engage a foot of a user in operative engagement therewith while limiting the movement of the foot relative to the foot fixings. Each of the foot fixings is operatively connected to a suitable mechanism that provides a resistance force to vertical movement of the foot fixing by the user's leg. In exemplary arrangements the resistance force may be selectively variable with regard to the magnitude and/or point of application so as to provide the desired training regimen.

In a first aspect, a method for monitoring a golf swing is provided that includes coupling a mobile telephone to a golf club and employing the mobile telephone coupled to the golf club to monitor acceleration of the mobile telephone as the mobile telephone swings while a user swings the golf club, collect acceleration information based on the monitored acceleration of the mobile telephone as the mobile telephone swings, analyze the collected acceleration information to determine one or more characteristics of the golf swing based on the collected acceleration information, and output information regarding the one or more characteristics of the golf swing on the display of the mobile telephone. Numerous other aspects are provided.

Disclosed herein is an exercise machine that includes an elongated frame having a head end and a foot end, and a moveable carriage slidably coupled to the elongated frame and moveable between the head end and the foot end, the moveable carriage having a spring bracket coupled to an underside of the moveable carriage. The exercise machine also includes a spring support rod slideably coupled with the elongated frame and disposed adjacent the foot end, and selectively positionable with reference to the foot end by a handle that extends from an interior area of the elongated frame to an exterior area of the elongated frame. The exercise machine also includes at least one resistive member coupled at a first end with the spring support rod and at a second end with the spring bracket, and configured to bias the moveable carriage towards the foot end of the elongated frame.

A slackline device comprising a main body having at least one bearing portion and two mutually opposite end portions which are disposed so as to be elevated in relation to the at least one bearing portion, and comprising a webbing which in an assembled state of the slackline device is tensioned between the two end portions of the main body. The slackline device is preferably portable. Strictly speaking, the slackline device disclosed herein is not a slackline in the actual sense, but is a device that is designed to realistically imitate the behavior of a slackline for the user.

An exercise machine inclination device for providing variable exercise intensity on an exercise machine by inclining the exercise machine. The exercise machine inclination device generally includes a base adapted for being positioned upon a floor, a support structure adapted for supporting the exercise machine, a hinge pivotally connecting the base and the support structure and an actuator connected between the base and the support structure, wherein the actuator adjusts an angle of the support structure.

A balance station for practicing balancing exercises made up of a platform, four legs, side rails, and a front rail. Different training exercises can be implemented by using different face plates for the base platform. The balance station provides a safe environment for stability challenge individuals to practice balance exercises.
