what are number of videos you used to train the bicep curl model?

Hi, I am checking out your repository, you did a great work in this, I wanted to know how many videos you used to train bicep curl model, I saw the csv contains 15k rows but as per code, it has been created by annotating the exercise videos, so I wanted to know the number of videos you used to create this dataset of 15k rows for bicep curl exercise.
