You Don’t Need Sit-ups To Build Core Strength, Try This Plank Workout Instead

Woman performs plank with leg lift on an exercise mat in her living room, a laptop is open in front of her.

If you want to build core strength, the plank is a great place to start. This bodyweight exercise activates all the core muscles—from the rectus abdominis (the visible six-pack muscle) to the transverse abdominis (the deep core).

I’m a personal trainer and I’m always telling my clients about the effectiveness of the plank—that’s why I’ve created this three-move core-strengthening circuit which takes 10 minutes.
