I have pain in the lower part of my back. When I go to the gym I try to not overload that part of my body. I just bought a foam roller to stretch out my back before and after my workout.
I also seem to have a 'flat lower back' when I bend over (red line), I can't bend any further because I hurst to bad otherwise (in the lower back):
What do you guys suggest I should do, keep stretching? See a doctor
