Crunches + interval ?

is it true that its bad to do crunches while on your time of year? I don't think so. Actually exercise help with cramps it doesn't rationale them.
?"It might cause your pelvis to return with stuck on one side" that is the dumbest item!
yes and no..yes bc ur muscles tighten causing u to find more crampy cramps.. and no bc us women r told to excerise during our periods.. soo try it if doesnt hurt u and bestow u more cramps(or worse) then dance 4 it.. it affects ppl differently!! Good Luck
