Weightlifting system and method for analysing lift motion

A weightlifting system for monitoring the symmetry of a lifting stance of a weightlifter, the weightlifting system including:

• a platform for supporting a weightlifter during a lift and/or handles for measuring hand force, the platform and/or handles including
• one or more support plates which include one or more load sensors, and/or a plurality of handles or handle adaptors for mounting on a dumbbell, barbell, crank or other handle or drive portion of an exercise device, the plurality of handles or handle adaptors including one or more load sensors;
• a processor in data communication with the one or more load sensors for receiving and processing weightlifter load data, the processor configured to assess weightlifter symmetry data against a symmetry threshold to provide a symmetry result;
• an output module or display for informing the weightlifter of, or displaying, the symmetry result;
• and
• a notification module for notifying the weightlifter based on the symmetry result;
• wherein the notification module comprises a vibration module which causes a portion of the weightlifting platform to vibrate, depending on the processor assessment of the weightlifter symmetry data against the symmetry threshold;
• wherein the vibration module is configured to vibrate at least a portion of the left support plate in a selected pattern if the weightlifter is leaning too far left, or the vibration module is configured to vibrate at least a portion of the right-hand support plate if the weightlifter is leaning too far to the right during or before a lift, or the vibration module is configured to vibrate a front portion of one or more of the support plates to indicate that the weightlifter is leaning too far forward.
