Shrink your middle and drop fat all over with this belly-busting plan.

THIS MONTH’S GOAL
Show your abs who’s really in charge.

Why these moves work
You clean up your diet to lose weight, now do the same for your workout. Those mindless crunches you can crank out for minutes at a time are the “junk” in your ab routine. If you can get past 25 reps with any move, you’re probably not engaging your middle muscles. We’re not saying crunches are bad, but you need to do a variety of moves—with focus and intensity—to flatten and firm your belly. The exercises here do the job by targeting your muscles from all angles with resistance. Now, consider your regimen de-junked!
