Put your mat away and give your neck a rest. “Standing abs exercises work more muscles than crunches—and the more muscles we use, the more calories we burn,” says Sara Haley, creator of The Daily Sweat workout DVDs and a Reebok Global Master Trainer in Santa Monica, CA. While sit-ups and crunches only work superficial surface muscles, standing moves strengthen deep core muscles that lead to a great six-pack.
Get off the floor and upgrade your core workout with these 13 standing core exercises. For maximum results and varying resistance, include body weight, medicine ball, dumbbell, cable, and kettlebell moves.
