An Oblique Workout for Women — and Everyone Else, Too

10 Oblique Exercises for Insanely Strong Abs (1)

While abs-focused workouts are great, a strong core isn't just about toning your transverse abdominis. (See: Why It's Important to Have a Strong Core) You should also be paying attention to your obliques, aka the "side abs." Strong oblique muscles will improve your posture and support your lower back, among other benefits.

But you're going to do more than just some crunches to fire up the obliques and work the full core. To give you some pointers, trainers from across the country shared their best exercises to build a smart oblique workout for women — or literally anyone who wants to strengthen their "side abs" muscles. Get ready to sweat!

How it works: Do all of these obliques exercises once through for a killer oblique workout, or pick your favorites and work them into your regular routine.

You'll need: a 12- to 15-pound kettlebell, plyo box or another elevated surface, set of 5- to 10-pound weights, small exercise ball (optional)

"I love this oblique exercise because it isolates and strengthens the obliques by keeping them fully activated over the entire range of movement, while also keeping the lower back fully protected," says Julie Jacko, Ph.D., a certified Pilates instructor and professor of public health.

What to Do If You Have Lower Back Pain From Running

A. Lie faceup, extending arms straight up overhead. Keeping core engaged, lift legs into tabletop position, knees bent at a 90-degree angle.
