Sometimes, we can get stuck in a rut of doing the same moves over and over. This is extremely common when it comes to a good core workout. For many, crunches are the only way to get the flat stomach they are after, but oh boy, is that not the case. Trainer Anna Renderer is here to prove that theory wrong. Using all kinds of core moves, she takes you through a ten minute core workout that will have your abs burning without doing a single traditional crunch! Out with the old and in with the new.
