Your Next Personal Trainer: Instant Evaluation of Exercise Form

1. Depth: Angle formed between the ankle knee and hip while squatting 2. Stance: distance between feet and center of mass over your ankles 3. Back-Hip Angle: Angle formed between the knees hips and back throughout the squat 4. Knee-Toe Alignment: Location and movement of knees throughout the squat • Certain components, such as required depth, stance and the angle at the hip, are fairly well-defined problems. • Logistic Regression with L1 regularization proved effective in reducing overfitting and identifying the well-defined decision boundaries. • Stance and squat depth error quickly levels out. We believe we are limited by the fidelity of Kinect’s coordinates and the accuracy of our labeling.
