Are planks or sit-ups better for working your abs?—S.C., Cambridge
Carve out some extra time on your mat, because you’ll need to do both.
Cote says sit-ups—and similar exercises such as crunches, leg raises, and reverse crunches—work your rectus abdominis, or the muscle we colloquially know as abs. Cote calls these “the six-pack muscles” because, when your body fat is low enough, they’re what shows beneath your skin.
“Regardless of your goal, it is important to include exercises that work the rectus abdominis because those exercises will strengthen the abdominal muscles and help build the abdominal structure,” Cote says.
But sit-ups and crunches aren’t all it takes to build a strong core. You also need to work your transverse abdominis, the layer of muscle deep within your abdominals that’s “responsible for stabilization of the torso and back,” Cote says. That’s where planks, and moves like dead bugs and bird dogs, come in. They work your deep abs as well as your low back, boosting functional strength and stability. (It can’t hurt to also work your obliques, or the sides of the core, through exercises including side planks, hip dips, and twists.)
“For a combination of functionality, strength, and aesthetics,” Cote says, “I recommend including variations of both exercises in your routine. “
