It's one thing to lose weight, but it's another to see a solid six-pack. In combination with a nutritious diet, you need to incorporate ab exercises, ideally combined with cardio as an effective means to combat belly fat. And the good news is you don't necessarily have to do 1,000 crunches to reach your goals. Try plank variations, wood chops, standing oblique dips, stability ball exercises, etc. Or sign up for yoga and pilates, which are both excellent forms of exercise for your core.
