A training and conditioning system including: a training and conditioning system assembly including: a plurality of weights; and a training manual. The training and conditioning system has a training and conditioning assembly; wherein each of the weights are configured to be manipulated by a user-athlete according to the training manual. The plurality of weights are unmarked as to how much each weighs so as to train a user-athlete mentally and physically to accomplish training regardless of weight randomly lifted.

A Pilates reformer accessory that couples with a Pilates reformer. The accessory includes a jumpboard, and in some embodiments, it also includes a ballet bar attachment. Jumpboards of the inventive subject matter have several regions on a surface that help a user practice jumps while using the Pilates reformer. The ballet bar attachment can be coupled with the jumpboard, and the ballet bar attachment can include a latching hinge that enables the ballet bar attachment to be easily repositioned relative to the jumpboard.

Disclosed herein are systems and methods that relate to a modular protective system designed to be worn or incorporated into a helmet that prevent collisions with other stationary or moving objects by providing a visual and/or audible signal to the user. The system is composed of sensors that provide both directional and velocity information related to objects within the device/wearers surroundings. A computer device receives this information and translates it into a collision path and notifies the wearer of a possible collision and its trajectory.

A sound-generating device is adapted to be fitted in a ball or other type of sports equipment and can aid location tracking by blind and visually impaired athletes during game play. The sound generated by the device is adapted for localization by the athlete in each of the x, y, and z planes. A shock sensor can be used to signal a sound generator to produce a different sound when a change of momentum or direction is detected.

A progressive lens has an optical center and a geometric center line. The progressive lens further comprises a first surface and a second surface. At least one of the first surface and the second surface is a free-form surface. The free-form surface comprises a nearsight region, a farsight region, and a transition region. The geometric center line passes through the nearsight region, the optical center, and the farsight region. A straight-line distance between a first reference point of the nearsight region and the optical center along a direction of the geometric center line is about 13 mm to about 25 mm. A straight-line distance between a second reference point of the farsight region and the optical center along a direction of the geometric center line is about 2 mm to about 5 mm. The disclosure also provides a progressive glasses.

A height adjustable combat training assembly and method of operation enables a practitioner to strike with a fist, kick, hurtle over, and reenact combat with a real person through use of a height adjustable series of shafts, target accessories, and elongated barriers that are manipulated into myriad configurations. A base portion is filled with a weighted substance to stabilize the assembly. A base shaft attached perpendicularly into the base portion. A height adjustable shaft extends from the base shaft in a sliding relationship that is measured with a height gauging instrument. Padded sleeves encapsulate both shafts for cushioning. A flexible member extends form the terminus of the height adjustable shaft. A terminal target rests on the terminus of the second sleeve. A label attaches to the sleeves. At least one target accessory detachably attaches to the shafts or sleeves, and includes linear arm, blocking arm, laser device, and fist.

A system and method for signaling users including a control device electrically connected to a transceiver. The transceiver has a specified frequency. A first mobile signal device being activated by a first user and electrically communicating with a first transmitter having a selectable signal frequency. The first transmitter electrically communicates with the transceiver using the specified frequency. A second signal device includes a second receiver for receiving an activation signal from the transceiver. The second receiver electrically communicates with the transceiver using the specified frequency. The second signal device is activated by the activation of the first mobile signal device using the transceiver for alerting other persons.

A bicycle simulator is arranged by arranging a front wheel and a rear wheel of a bicycle on the same plane. The bicycle simulator includes a front roller that supports a front wheel of a bicycle that is mounted and rotates together with a rotation of the front wheel, The bicycle simulator further includes a rear roller that supports a rear wheel of the bicycle and rotates together with a rotation of the rear wheel. A first support point at which the front roller supports the front wheel and a second support point at which the rear roller supports the rear wheel are arranged on the same plane. Not only a substantially flat ride path but also various ride modes in which an inclination angle may be adjusted according to a ride mode may be implemented, and a dynamic experience similar to the actual ride situation may be enjoyed.
