The 2008 Drop a Jeans Size Workout

Plan by trainer Kristi Molinaro, creator of the 30/60/90 workout at Equinox Fitness Clubs in New York City

These exercises will burn fat, tone muscle, and boost your metabolism. Challenge your body by combining strength and cardio exercises, and you'll be struttin' in your skinny jeans in no time.

Combo 1: Jump Rope/Row

Strength: Row (targets upper back)

Stand holding both weights in right hand, arm at side with palm facing body; place left foot forward. Hinge forward 45 degrees from hips, resting left hand on left thigh. Draw weights to ribs, keeping elbow close to side; lower weights and repeat. For the second set, switch sides. For the third, keep feet aligned and use both arms, one weight in each hand.

Make it easier: Use just one weight for the one-arm rows.
