Here is something that probably will seem controversial
Your belt is not bracing for you…⠀⠀⠀⠀⠀⠀⠀⠀⠀
You should only belt up if you are going 80% or heavier.
The belt is just a support tool to REMIND you to engage your midline. A belt does not engage it for you. The belt is a tool to enhance performance – aka help you lift really heavy – not to protect you from pain or injury. ⠀⠀⠀⠀⠀⠀⠀⠀⠀
If you need your belt in order to brace, or if you need a belt in order to brace enough to not have pain, get rid of it. Build core strength instead and learn to use your body.
Your belt should give you a competitive edge, nothing more.
