Slim thighs are nice. Trim, taut arms are great, too. But there's nothing like feeling your abs get firmer, flatter and so toned you can't wait to wear a two-piece--particularly now that it's high beach season. Hello, hot weather!

The good news: You don't have to employ a celebrity trainer or be 18 to have a waistline worth baring. The secret to a getting a trim belly--not to mention fit from head to toe--is tailoring your workouts according to your birthday. (Not that anyone will guess how old you are, once you start exercising consistently.)

Science shows that frequent sweat sessions can actually help you be forever young: When researchers studied the lifestyle habits and DNA of 2,400 twins, they found that regular exercisers had longer telomeres, tags at the ends of chromosomes that shorten with age, than their couch potato counterparts. In fact, as little as 30 minutes of activity daily resulted in telomeres that looked 10 years younger.

Follow the age-specific advice below and then try the get-lean routine:

In your 20s: You're energetic and resilient, so it's the perfect time to make fitness a key component in your life. The following moves will help you sculpt sexy muscles and build bone, which is crucial for warding off osteoporosis in the future. Try using heavier weights than you're used to (doing the final rep should be challenging) and adding a third weekly session when time allows.

In your 30s: Reality check--there's a natural 5 percent dip in metabolism during this decade. But you can still be a lean fat-burning machine by doing the moves below. They will build muscle, which will naturally rev your metabolism so you torch more calories even in your sleep, as well as bolster core strength and maintain agility.

In your 40s and beyond: Sexy curves you have. Now you want to stay firm and injury-free. These shapers will help you boost your backside (an area which may naturally lose muscle as you age) and tone all over. To increase your flex appeal and decrease your overall injury risk, add a weekly yoga class or regular stretching to this routine.
