Could over arching of the back lead to back problems in the long run? Because ive been lifting for around 2 years and ive noticed in the mornings after a squat day, my back has a dull ache. Its now to the point were ive got this ache all the time but only when my body is in certain positions. Its not the lower back but more where the arch starts, half way up.
And also, when squatting, should you start with the arch before decending? I tend to kick my hips back into the arch and then at the top lock my hips forward out of the arch.
