Abstract: The Positional Offset Weight System is an extendible tube assembly with an attached weight that provides the user with a rapid adjustment mechanism to set resistance. The device can be used for a wide variety of exercises by reducing mechanical advantage. This allows the user to use a single light weight to achieve results that normally requires a variety of heavier weights or equipment. The device or system uses a twist or friction lock to adjust the length of the tube based on desired resistance, stability and range of motion.
