An exercise accessory includes a load bearing element. It further includes a haptic actuator. In response to an indication of an event pertaining to a load on the load bearing element, the haptic actuator is configured to generate a vibration pattern corresponding to the event. Different events are associated with different vibration patterns.

An exercise system includes a load bearing element having a control element. It further includes a resistance mechanism responsive to a signal from the control element. The signal from the control element is selectively rejected based on state information relating to a state of the load bearing element.

A wobble board includes a platform, a base having a generally flat bottom surface, and at least one compressible member positioned intermediate the platform and the base such that the platform is pivotable with respect to the base.

In response to physical connection of an exercise accessory with a portion of an exercise machine, an identifier of the portion of the exercise machine is received. A signal including the identifier of the portion of the exercise machine is transmitted.

An exercise system includes an exercise machine and an exercise handle coupled to the exercise machine via a cable, the exercise handle comprising a set of sensors. The set of sensors is used to detect a location of a portion of a user's hand on the exercise handle.

A balance board, including: an upper plate having a top surface configured for a user to stand on; a base assembly configured to contact the ground; a center assembly pivotally connecting the upper plate with the base assembly; and an adjustable tilt system comprising at least a first adjustable angle stop configured to be rotated at adjustable intervals to change a maximum angle by which the upper plate may be tilted relative to the base assembly. The base assembly may include a first plurality of teeth. In addition, the first adjustable angle stop may include a second plurality of teeth configured to interface with the first plurality of teeth of the base assembly to provide fixation of the first adjustable angle stop at the adjustable intervals.

In response to physical connection of an exercise accessory with a portion of an exercise machine, an identifier of the portion of the exercise machine is received. A signal including the identifier of the portion of the exercise machine is transmitted.

An exercise device having a unique asymmetrical shape with rounded ends of differing radii to provide stability and added resistance.

A balance board may include an upper plate having a top surface configured for a user to stand on; a base assembly configured to contact the ground; a center assembly pivotally connecting the upper plate with the base assembly; and an adjustable tilt system comprising at least a first adjustable angle stop configured to be rotated at adjustable intervals to change a maximum angle by which the upper plate may be tilted relative to the base assembly.

An endless rope trainer that includes an upright frame, a drive roller supported a distance above ground on the frame, an endless rope entrained around the drive roller, and a means of applying resistance to rotation of the drive roller. A pair of guide rollers are provided proximate the drive roller. The guide rollers pivot together as a unit about the axis of the drive roller independently of the drive roller for maintaining a constant wrap angle of contact of the endless rope on the drive roller regardless of pull angle on the endless rope.
