Comparative Performance of Deep Learning Architectures
This table summarizes the performance of the three deep learning architectures—LSTM with Attention, GRU with Attention, and Transformer—across 10 randomized runs, along with their statistical significance.
| Model | Mean Accuracy | Standard Deviation | Interpretation (vs Transformer) |
|---|---|---|---|
| LSTM + Attention | 0.9890 | 0.0063 | Significantly better (p < 0.01) |
| GRU + Attention | 0.9897 | 0.0092 | Significantly better (p < 0.01) |
| Transformer | 0.9657 | 0.0205 | Baseline |
Key Takeaway: Both LSTM and GRU models consistently achieved superior accuracy and stability compared to the Transformer, highlighting the advantage of recurrent architectures with attention for temporal exercise data.

Personalized AI: The Role of Demographic Data
Challenge: Generic AI models often struggle with diverse user populations due to variations in body proportions, athletic experience, and movement patterns. This limits the accuracy and effectiveness of automated coaching systems across all users.
Insight: This study found that participant-specific features, such as athletic experience and Body Mass Index (BMI), significantly affect classification accuracy. Participants with higher BMI and lower training experience showed slightly increased misclassification rates, indicating that anthropometric variability influences movement execution and, consequently, model performance.
Enterprise Application: Integrating demographic and anthropometric covariates into AI models enables a more personalized and equitable feedback system. This multi-branch fusion approach can improve discrimination between visually similar movements, reduce inter-user variability, and ultimately lead to more effective and trustworthy AI coaching for a broader range of users in fitness, rehabilitation, and sports analytics.
Autonomous Exercise Coaching: Bridging the Expert Gap
Opportunity: The demand for personalized and accessible exercise guidance often outstrips the availability of human experts, leaving many without proper supervision, leading to potential injury or ineffective training.
Solution: The research demonstrates the feasibility of AI-based feedback systems that provide automated, immediate, and interpretable guidance during exercise. By leveraging dual-camera pose data and robust deep learning models, the system helps users adjust their form in situ, mitigating injury risk and enhancing training efficacy without retrospective correction.
Impact: This technology offers a scalable solution to bridge the gap between expert supervision and autonomous physical practice. It supports safer and more effective training in both athletic and everyday health contexts, laying the groundwork for truly expert-free, real-time exercise coaching and rehabilitation systems. Future advancements include integrating multi-modal inputs (depth, IMU) and rigorous "in-the-wild" testing for broader generalization.
