Weightlifting Belt

Hello, I am beginning to look into buying a weightlifting belt. I am running the beginner program. I wanted to know if there is a certain point in training when you feel that a belt would be recommended for deadlifting? Also would you recommend using a belt for performing squats? Thank you.

Here’s a video from a few years back on the topic that should help get you started: https://www.youtube.com/watch?v=3coLPynaROs
