Just curious if this is a possible/true
my lower back has been pretty tight today as well as my hip flexors. Then I did box squats and it didn't do shit but make it 10x worse. (Then step ups, then rack pulls and i had to grit my way through those)
After I stretched out my hip flexors I was fine, my back didn't even bug me
I was wondering if there was an anatomical reason for this... Like are the lower back muscles and hip flexors tied together?
