Here is the bottom part of an RDL rep. I swear I’m trying to keep my back straight. Is that rounding normal? I also notice it on other exercises. I have a ton of back pain.

I have a 10 gallon terrarium with thriving isopods and springtails. It stays at around 80% humidity and it’s about 7 months old. It’s pretty small, but I’m wondering if anyone knows of a critter that would thrive in this setup.
