An exercise bar, shaped like a motocross handlebar, that be attached to any multifunction gym. The user grips the bar as he/she would grip a regular motocross handlebar when working out, which works those muscles in the hands and arms that normally are used in motocross riding. A support bar is added to the top portion of the bar for added stiffness and to provide support for a retractable shaft for pulling exercises. A telescoping hook is also provided at the bottom to support a dumbbell that can be suspended at the bottom of the bar. The extended arm portions of the bar are fitted with locking hinges that allow the bar arms to fold for storage or for travel. A kit is also disclosed that allows the conversion of a standard handlebar into an exercise bar.
