Get abs of steel by doing THIS!
If you want abs of steel, skip the crunches and planks, and do cardio! Yes, planks strengthen your core, but you won’t SEE that core without aerobic exercise. In fact, exercise scientists from Auburn University found people doing abs exercises for 6 weeks lost NO abdominal fat, because we can’t spot-reduce fat. But consistent aerobic exercise, like running or swimming, plus strength training and cutting calories DOES lead to weight loss, everywhere on your body, including your stomach.
