Angling to get the firm abs of a Victoria's Secret model? One personal trainer insists that sticking to sit-ups won't get you there.
"Just doing sit-ups alone won't get you rock hard abs because you're only working to strengthen one singular area, which is like trying to build the outer layers of a house with no foundations underneath," she explained.
It means that unless you're doing sit-ups as part of a greater work-out routine —— like with cardio and planks —— you shouldn't expect to see any visible results when looking at your tummy in the mirror.
