Good posture and form are essential for safe and productive exercising. Even
in gym settings, trainers may not be readily available for feedback.
Rehabilitation therapies and fitness workouts can thus benefit from recommender
systems that provide real-time evaluation. In this paper, we present an
algorithmic pipeline that can diagnose problems in exercise techniques and
offer corrective recommendations, with high sensitivity and specificity in
real-time. We use MediaPipe for pose recognition, count repetitions using
peak-prominence detection, and use a learnable physics simulator to track
motion evolution for each exercise. A test video is diagnosed based on
deviations from the prototypical learned motion using statistical learning. The
system is evaluated on six full and upper body exercises. These real-time
recommendations, counseled via low-cost equipment like smartphones, will allow
exercisers to rectify potential mistakes making self-practice feasible while
reducing the risk of workout injuries.

通过使用 MediaPipe 进行姿势识别、峰值检测来计算重复次数以及使用可学习的物理模拟来追踪运动演变，本文提出了一个算法流程，可以实时检测和纠正运动技术问题，并通过统计学习基于典型学习运动来诊断测试视频。这个低成本设备如智能手机支持的实时推荐系统将帮助锻炼者纠正潜在的错误，使得自我练习成为可行的同时降低锻炼伤害的风险。
