FitAQA - Temporal Grounding: leaderboard

FitAQA (Tsinghua University, 2026) evaluates multimodal LLMs on fitness action-quality assessment over 30 bodyweight exercises and a 38-error taxonomy. Temporal grounding mean IoU measures how well the model localizes the intervals where a described form error occurs, in percent, higher is better.

Metric: Mean temporal IoU (%; localizing the intervals where a described form error occurs; over FitAQA's fitness action-quality videos (30 bodyweight exercises, 38-error taxonomy); temporal grounding task). Source: arxiv.org. Saturation forecast: Around July 2027. 18 models tracked.
