The recording device for weightlifting is removably attached to one end of the bar of a barbell set and holds a marking or tracing implement (e.g., chalk, whiteboard marker, laser pen, etc.) removably therein. A board (for use with a marking implement) or light recording screen (for use with an optical device) is positioned near the marking or tracing implement, the marking implement being in contact with the board. The weightlifter may then perform lifts while recording the path of the bar on the board or screen by means of the marking or tracing implement. The resulting trace enables the lifter and/or his or her coach, mentor, or assistant to determine accurately the path of the bar during the lift, thereby facilitating the determination of any corrections that might be needed to the form of the weightlifter during lifting exercises. |
