9 Standing Ab Exercises That Work Your Entire Core

Standing ab exercises are low-key multitaskers. They improve your posture, boost strength in your entire body, and test your balance, says fitness trainer Kim D'Agnese. Here are nine moves that’ll bring the burn, no crunches necessary.

D’Agnese’s Twist Marches

- Stand with feet parallel.

- Bring elbows to shoulder height with arms in front at 90-degree angle.

- Lift 1 knee, bringing elbow to opposite knee.

- Challenge: Squat between each knee lift.

Do 2 sets of 1 minute each to work your entire core & obliques.
