Singing bass relaxed

Hello everyone.

I recently figured out I am squeezing my lower notes and forcing them instead of singing them relaxed. Also squeezing to make them more resonant. I started singing relaxed and they are quite and I only managed to get to F2 relaxed while I could get to Es2 or D2 before consistently. I want to know if anyone has tips on how to go lower relaxed. How do you guys get relaxed enough I mean the throat to do low notes?

Thanks for help in advance!
