An information related to the position of an actuator coupled to a cable which is coupled to a motor is received. A filter is used to provide an input to a motor controller coupled to the motor, to adjust torque on the motor such that a strength curve is implemented relative to the position of the actuator.

System and method for launching a ball onto the ground of a playing field. The system includes an outlet chamber configured to receive the ball therein; an outlet conduit or frame configured to contain the outlet chamber and allow the same to move through the outlet conduit towards a second position on the ground; movement capability of the outlet chamber, connected to and configured to move the outlet chamber between at least the first position and the second position, where the outlet chamber includes an outlet mouth and launching means for launching the ball arranged in the outlet chamber. A field including the system is also described.

A locker includes a pair of spaced-apart upstanding sidewalls and at least one shelf extending between the sidewalls, the shelf and sidewalls defining a compartment. A rack is disposed in the compartment and extends upwardly from the shelf. The rack is dimensioned and configured to support at least a pair of shoulder pads and preferably both pads and a helmet. The rack optionally includes a ventilation system, and the ventilation system may be incorporated into a multi-locker ventilation system.

Disclosed are a folding treadmill and a folding method. A folding method of a folding treadmill includes the following steps: unlocking a pin lock assembly to enable a column assembly and a running platform to be in an unlocked free state, then unfolding or folding the column assembly to be in an unfolded state or a folded state relative to the running platform, and locking the pin lock assembly to complete the unfolding or folding of the treadmill. By means of the pin lock assembly, the column assembly can be firmly locked on the running platform no matter whether the column assembly is in the unfolded state or the folded state, thus not only achieving rapid unfolding and folding, but also ensuring the stability of the unfolded state or the folded state, and improving the safety of the folded state.

A folding exercise rack system for providing an exercise rack that may be easily and compactly stored when not in use. The folding exercise rack generally includes a plurality of extension members pivotably connected to wall-connected mounting brackets. Upright support members connected to the extension members support a barbell and exercise bar. The exercise rack is pivotable from an extended exercise position into a plurality of selectable compact storage positions substantially parallel with and closely adjacent to the wall. The mounting brackets include a plurality of selectable connection points to determine how much space is present between the wall and exercise rack in the storage positions. One connection point allows a retractable exercise bench to be stored in the space between the wall and exercise rack. Mechanisms are provided for locking the exercise rack in a plurality of selected positions.

The baseball/softball hitting training device includes a base, a frame body, and a ball suspension system. The ball suspension system is supported by the frame body. The frame body includes a vertical stem portion and an offset portion. An upwardly-projecting arm of the vertical stem and a downwardly-projecting arm of the offset portion define a vertical axis between them. The ball suspension system is supported between the upwardly-projecting arm and downwardly-projecting arm, with the ball held vertically intermedially via a tether in alignment with the vertical axis and positioned to allow the player to practice hitting. In some aspects, a height-adjustment mechanism and/or additional coupling assemblies are also disclosed. The tethered-ball training device can optionally be converted to a tee-ball training device.

Assisted racking of digital resistance includes detecting a state of a cable. A motor is mechanically coupled to the cable to provide resistance during an exercise by tensioning the cable. It further includes determining completion of the exercise based at least in part on the detected state of the cable. It further includes selectively removing resistance from the cable based at least in part on the determination that the user has completed the exercise.

An article of manufacture providing an exercise device for work-out with a stroller according to the present invention includes the stroller having a frame having a front portion and a rear portion, a front wheel assembly coupled to the front portion of the frame, a pair of rear wheels coupled to the rear portion of the frame and a handle coupled to the rear portion of the frame above the pair of rear wheels and a plurality of barbells coupled across the stroller for supporting removable weights on both ends of the barbells. A first barbell coupled across the rear portion of the frame between the pair of rear wheels and the handle. A second barbell coupled across front wheel assembly. A third barbell coupled across the handle.

An adjustable resistance apparatus includes features that protect a user from harmful heat generated during use while offering a wide range of resistances. The apparatus may be combined with a variety of accessories, such as a load cell.

An exercise machine is disclosed. The exercise machine comprises a motor. The exercise machine comprises a gearbox coupled to the motor, wherein the gearbox comprises bevel gears. The exercise machine comprises a spool coupled to the gearbox. The exercise machine comprises a cable wound about the spool.

A second exercise machine is disclosed. The second exercise machine comprises a motor. The second exercise machine comprises a lockable translatable mount. The second exercise machine comprises a cable coupled to the motor via the lockable translatable mount. The second exercise machine comprises a sensor coupled to the lockable translatable mount, wherein the sensor is used at least in part to determine mount lock state.

A third exercise machine is disclosed. The third exercise machine comprises a motor. The third exercise machine comprises a mount. The third exercise machine comprises a cable coupled to the motor via the mount. The third exercise machine comprises a sensor coupled to the mount, wherein the sensor is used at least in part to determine mount lock state. The third exercise machine comprises a lockable arm coupled to the mount and a second sensor coupled to the lockable arm, wherein the second sensor is used at least in part to determine arm angle.
