Mr. Woodhull...
I can work on trimming down
Not sure how my teachers would feel about me standing in class though
But you're not the one who asked about lordosis... lol
You probably don't have hyper-lordosis so you don't need to do that stuff. Not that trimming down or stretching daily is bad for anyone (stretching is massively underrated for muscle tone and overall fitness) but you don't have to worry about standing in class because it's unlikely that you suffer from extreme lumbar curvature. Although, if you took notes and all that jazz, no reason to see why a teacher would not allow it, if you explained that you were suffering from lower back pain and poor posture and it was scientifically proven to correct itself by sitting as little as possible and performing hip stretches.
Edit: Nevermind, I saw that you did look into it after the other guy asked about it. Well, eat your lunch standing up and don't sit around a lot when you're at home. Do the other stuff like trim down and make sure to stretch every day. Supposedly the best way to remedy it is hip-flexor stretches, daily, so look those up specifically.
