Crush this quick 15-minute workout and you’ll have toned abs in no time! Each movement works your entire core—abs, obliques and lower back.

Building core strength is about so much more than physical appearance. It improves your posture and balance, increases your stability, supports your lower back, strengthens your spine and helps you go about everyday tasks with ease. The ripple effects of a strong core can improve your overall quality of life.

• 15 minutes

• Abdominals and entire midsection

The exercises in this routine target your entire core, including your rectus abdominis (the muscles most of us call “abs”), internal and external obliques (the outermost muscles on the sides of your torso), transverse abdominis (your deep core muscles), pelvic muscles, diaphragm, glutes and back.

• An exercise mat (optional for comfort)

Begin with a quick Warmup. You can do jumping jacks, go jog around the house for a minute, or choose one of our warm-ups from the exercise library.

Complete the Core Circuit. Focus on the motions of each move and execute them slowly and with intention; maintain control and keep your core tight.

After completing the workout, end with a short Cooldown. March in place, stretch, break out some of your favorite yoga poses, or choose one of our cool-downs from the exercise library.
