You're so vain

We quizzed Andrea Colvin, a personal trainer at Lincoln Park Athletic Club, for some exercises to help us pull off this season’s fashion fads.

The trendFlats
The rub You can’t fake leg definition without wearing heels, so focus on toning your calves.
The fix Plié squats with heel raises. Stand with feet wider than shoulder-width apart. Squat down keeping your shoulders over your hips. Then raise each heel off the floor (keeping the balls of your feet stationary) and alternate feet. Do 10 to 15 reps per foot.

The trendHigh-waisted pants
The rub Face it, everyone’s going to be looking at your ass in these tight-fitting pants, so you’re going to have to work hard for a firm, perky bum.
The fix One-leg squat reaches. Stand on one leg, bending your supporting knee and reaching toward the floor while squeezing your glutes. Do 8 to 15 reps and repeat with the other leg.

The trendSlim suits
The rub Slender cuts are hard to pull off for dudes who are on the chubby side. To burn fat, amp up your cardio to 30 to 60 minutes, five times a week. Also, do sit-ups to firm your midsection.
The fix V-crunch obliques. Sit on your butt with arms extended behind you for balance, knees raised with calves parallel to the floor. Rotate your hips to one side and extend your legs while rotating your torso in the other direction. Repeat on the opposite side. Do three sets of 8 to 15  reps.

The trendDresses
The rub Toning your shoulders and chest are the keys to looking feminine (not flabby) in dresses.
The fix Walk-out push-ups. Stand with feet slightly closer than hip-width apart. Bend over, placing your hands on the floor, then walk your feet back until your body makes a straight line from ankles to head. Do a push-up and walk back to the start position. Do three sets of 8 to 15 reps.

The trendPolo shirts
The rub Short sleeves mean your arm muscles are going to be on display. So sculpt showcase-worthy biceps and triceps.
The fix Triceps dips. Find a bench, chair or step and place your hands on it, with palms facing away from your body. Dip down until your upper arms are parallel with the floor. Pause and push back up to starting position. Do three sets of 8 to 15 reps.
