Put on a belt. Does the buckle point down rather than straight out? When it’s leg day at the fitness gym, do your hamstrings feel tight and sore before your quads?

This means you have weak hip flexors, lower spine muscles, or lower abdominals, and it’s common among people who sit for many hours at a time. - Dr. Maria Jennifer Pinto (P.T.)
