Your legs Amazing Runners World Show efficiency when you run. In fact, when college athletes incorporated an eight-week core training program into their schedule, they improved their running economy, according to a 2019 study published in PLoS One, which is a measure of how fast you can move with a given amount of oxygen. The more economical you are as a runner, the easier running feels. Those who did the three-times-a-week workout also improved their balance What to Know About VO2 Max as You Age.

Because a strong core is so important to running, Lindsey Clayton, chief instructor at Barry’s in New York City and cofounder of the Brave Body project, designed this lower ab workout with the best exercises for runners.

The Benefits of Lower Ab Exercises for Runners

One quick anatomy note before we get to those lower ab exercises: There isn’t a specific way to isolate and train your lower abs—that’s actually a common misconception about your core.

“Your core is comprised of the rectus abdominis, which runs down the front of your body and creates that ‘six-pack’ effect; your obliques (side abs); your erector spinae, which runs up your back; and your transverse abdominis (the deep core muscles located under those six-pack muscles),” says Clayton. “When people point to the lower part of their stomach and say their ‘lower abs,’ they’re typically just referring to their rectus abdominis, and you can’t only work the lower part in isolation.”

But practicing these ab exercises can help you achieve the results you desire. That said, there are plenty of core exercises—both creative and classic—that engage your rectus abdominis, including your lower abs, and make you a stronger runner.

“While it’s important to work your whole core for a balanced body, there are certain exercises that utilize the lower part of the rectus abdominis,” Clayton says. “These ‘lower abs’ exercises are great for runners because they often involve driving your knee up towards your core, simulating the Slide back to lower hips back to plank position.”

The benefits of working your core (in addition to improving efficiency and economy!) is that it helps to prevent injuries and stabilizes the center of your body, allowing your chest to stay upright, arms to swing back and forth, and legs to move forward with power and speed. Essentially, it helps to limit side-to-side or rotational movement so you have more forward momentum.

rely on a strong core to move with: Clayton suggests doing each exercise in the lower abs workout below for 30 to 45 seconds before every run as a warmup, doing just one round. “This will fire up your muscles so they’re active when you need them most,” Clayton says. If you want to do them as a workout on their own, go for two or three rounds.

Clayton demonstrates each lower ab exercise so you can learn proper form. You will need a mat and a set of sliders. Two hand towels or paper plates will work, too.
