I post here, because my post was auto-deleted from /r/fitness. My account is "too new" lol

What should I do? Should I just force myself to sit trough it?

For lifting I do 5/3/1, so that's not like a lot of lifting... 2-3 times a week + mma ~6 hours per week. That's all my physical activity except cycling (back feels ok). I'm not really sore from it, coz I sleep 8-10 hours + count my macros :)

My posture is ok according to my GP, maybe some small lumbar lordosis (but that's a self-diagnosis, it's continuing to look better and better the more I can lift though :) )
