Instant Ab Flatteners

Achieving a toned, sexy tummy might seem like a pipe dream this time of year. Baggy sweaters abound, egg nog is served and Frosty the Snowman doesn't offer much in the way of flat-belly inspiration. But getting a sleek, sexy stomach is easier than you think. Spend just five minutes a day on toning your abs and you'll get an amazing middle.

We rounded up five of the most effective tummy toners around. Work three or four of these exercises into your routine (easing them in will minimize soreness). Do the number of reps indicated, resting one minute between moves. The only equipment you will need is a hand towel. Washboard abs, here you come!
