Monitoring exercise activity in a gym environment

A system for monitoring exercise activity in a gym environment, said system comprising:

• an image-based monitoring arrangement configured to generate a time series of 3D representations of an individual in the gym environment, wherein each of the 3D representations defines a pose of the individual and comprises positions of a plurality of predefined feature points of the individual in a 3D coordinate system;
• a storage device configured to receive and store at least part of the time series of 3D representations, said at least part of the time series corresponding to an exercise performed by the individual, and a replay device configured to retrieve said at least part of the time series from the storage device, render an animation of the individual when performing the exercise based on said at least part of the time series, and provide the animation for display,
• wherein the replay device is configured to process said at least part of the time series to evaluate performance of the exercise performed by the individual and combine a performance indicator representing the performance with the animation,
• wherein the replay device is further configured to process said at least part of the time series to classify the exercise performed by the individual into an exercise category among a plurality of exercise categories, and to evaluate the performance based on the exercise category.
