PostureGuardian

Posture Guardian is a Telegram bot that uses AI to determine if your deadlift has the right posture, mostly so you don’t hurt yourself, and it can also document your progress plotting how good your posture is relative to time.

For this project we created our own dataset of correct/incorrect postures and trained a model ourselves, but training a model on raw images was inefficient and introduced a lot of noise, so we actually use two AI models for the project: one to capture the human posture, and one that just based on the posture information determines if it’s right or wrong. The first model is a preexisting one, and it outputs an array of numbers representing each joint and body part in space. The second one is the model we trained ourselves, using posture data we mannually classified as correct/incorrect.

We built the project in python, and it has code for training based on a classified dataset, testing the results with new classified data to see the model’s accuracy, versioning models so you can test them and see what works best for what and the bot itself that uses the model to evaluate the posture in a picture.

It’s just a proof of concept because the accuracy of prediction is not always great and also we classified the dataset ourselves without the supervision of someone that really knows about posture, so I wouldn’t really trust it to give me advice. But the code itself seems to work, and with a more carefull dataset and maybe adding more supported exercises it may be a usefull program for people that train at home.
