Abstract: A personal lighting device includes a first housing including a light projection portion including an inner threading and a first protrusion. It further includes a second housing including a lighting mechanism cavity, an outer threading, a second protrusion, and a third protrusion; the second and third protrusions having a first space and a second space between the second and third protrusion, the second housing interconnected with the first housing via the threading, the first protrusion having a first and second position, the first position between the second and third protrusion in the first space, and the second position in the second space. The personal lighting device further includes a battery, a printed circuit board, and a light emitting diode such that when the first protrusion is in the first position, the LED is not activated; and when the first protrusion is in the second position, the LED is activated.

Abstract: The invention provides an exemplary barbell holder and methods for its use. In an exemplary embodiment, a barbell holder comprises a base member having at least one region that is adapted to hold a weight. A coupling mechanism is operably attached to the base member. The coupling mechanism is adapted to removably couple a barbell to the base member.

Abstract: The invention provides an exemplary barbell system and methods for its use and construction. The barbell system comprises a handle having a pair of ends, and a pair of end pieces which are receivable into each of the ends. The end pieces are adapted to couple a weight to the handle. A releasable coupling mechanism is provided at each of the ends to releasably couple each end piece to the handle. Further, a locking mechanism is provided and is receivable about the handle to lock the coupling mechanism in a locked position.
