So, my lower back is prone to being sore - on and off - several months no issue, then it gets sore. I did a HITT class on Sunday, it was so-so...then nothing until today - did a Boxercise class - and it's been sore since then again.
I know my glutes don't
firing up as best as they can, but I thought they were getting better., But I do a lot of exercise, all different sorts to strengthen whole body.
Any thoughts on a) what might be causing it b) what I should do to prevent it getting worse?
