Squatting too deep without belt

Hey Doctors,

I’ve only used the belt for the competition lifts as you guys recommend. I hit proper depth just below parallel and catch a good bounce when I use the belt.

However, when I do my squat variations (w/o belt), I end up going ass to the grass and have a tendency to relax/lose tightness at the bottom position.

I have pretty long femurs so I lean forward quite a bit, which makes my low back very fatigued and I get a low back pump when I do my squat variations.

So I wonder if I should start using a belt when I do the squat variations or not?

Thank you for your time.

You could start using the belt more. However, it’s not clear why the absence of a belt results in you losing control in the bottom. My preference would be to fix that issue, of course.
