15-Minute Workout: Toned To The Core

Hitting your muscles from all angles is the abs-olute best way to sculpt a tight, sexy midsection

Fast Core Workout for Women

If your abs routine consists of crunches, crunches, and more crunches, you may still have some jiggle around the middle. That's because the crunch works only one part of your core, and in a very nonfunctional way, which won't cut it if you're trying to reveal a slim waistline. To do that, you have to recruit your entire core, which includes your hip flexors, lower back, and glutes, plus all layers of your abs: the rectus abdominis, obliques, and transverse abdominis. You also have to work these muscles from every angle—not just front to back as the crunch does.

This routine, created by New York City trainer and strength coach John Romaneillo, targets your entire core with functional, up-off-the-floor moves. It's more effective than spot-sculpting your six-pack muscles, and because you're engaging so many more muscles with each move, it increases your body's fat-burning power. Oh, and your core is just the beginning. You'll also tone your arms, chest, shoulders, back, and legs. (Want even more unique abs exercises? Try these 4 Core-Sculpting Moves from Jillian Michaels.)

Complete this circuit by moving through the exercises without resting. Start with four circuits, resting for 60 to 90 seconds between each set. Too easy? Build up to five circuits or drop the rest to 45 seconds.
