The shape: Women with ruler-straight body types, like Cameron Diaz, can wear nearly anything—but they don’t generally have the girl curves to really kick it up in a bikini. Any weight they do carry usually forms a little potbelly, just like the boys get. Straight/boyish builds are similar to athletic types in that they also carve a fairly square silhouette; but unlike their athletic counterparts, boyish builds tend to have a tough time getting muscle tone.
The Rx: To add some curves, women with straight builds should focus on tightening their core—especially their deep abdominal muscles which pull in the belly, and the obliques, which cinch in the sides of the waist. Straight/boyish body types should also increase weight training to add lean muscle mass (read: curves) to their butts. Upper- and middle-back exercises will help un-hunch a square-body-type’s shoulders, lessening the frail-looking frame.
Monday: For each exercise shown, do 1 set of the prescribed repetitions, rest 30 seconds, then do another set of that same exercise. To amp up your results, follow your strength workout with a round of Smart Cardio Intervals.
Wednesday: Perform the moves circuit style: Do the prescribed number of repetitions for each exercise, with no rest between exercises. After you’ve done all of the exercises once, rest two minutes. Perform the entire circuit 3 times, resting two minutes between each circuit.
Friday: Perform each set of two exercises back-to-back, with no rest between each exercise. Rest 30 to 60 seconds before repeating the set one more time.
Nothing scorches calories or firms your muscles like fighting gravity. Follow your Friday strength-training sequence with the following Butt-Busting Hill Repeats—which can be done on a treadmill, elliptical trainer, or stationary bike.
