I'm at the phase of my training where I'm taking a lot of high falls, and I love it!
Now the thing is, after every training session my lower back got quite uncomfortable. Any movement bending my back is very uncomfortable and very annoying. I wouldn't say that it hurts though. If it hurts then I guess it's something dangerous.
My Sensei makes us do a lot of stretching techniques after class, but this problem persist.
Anyone has the same problem and a few advices on what I should do?
