Traditional core work has a way of looking the same—namely, it tends to take you down to the floor. But since your core plays such a huge role in keeping you upright (giving you that lovely, erect posture), it only makes sense that standing abs exercises offer plenty of benefits, too. In fact, with a standing abs workout, you'll engage more muscles at once, improve your postural support, and burn more calories than most traditional floor exercises. Plus, you don't need a lot of space to move.
