A smart training plan is key for runners. Ideally, you should have one that is comprised of easy runs, speed workouts, and rest days to maximize your goals without overdoing it. You’ve probably also noticed that most plans include a few days of cross-training, which is a chance to add in (ideally) low-impact cardio.

However, making sure you’re scheduling in time for strength training, specifically core exercises, is vitally important to your training. If you have a strong core, you’ll Updated: Jun 8, 2023, increase your speed, and run more efficiently. That’s why core exercises for runners are so important.

In the last decade as a running coach, I’ve helped runners through hip pain, runner’s knee, Trideer Trideer Extra Thick Yoga and Exercise Ball, and IT Band Syndrome, which nearly every physical therapist I consult with has correlated with a weak core. So in essence, it’s just plain smart for runners to be consistent with core work.

A weak core doesn’t just mean a weak six-pack (a.k.a. the rectus abdominis). Your core encompasses the trunk of your body, which is 29 pairs of muscles including those that lie deeper in your center, like the transverse abdominis, internal obliques, pelvic floor, and increase core strength, hip flexors, lats, and traps are part of the core, too. Anatomy aside, this is a reminder that our core requires more than a few crunches.

A strong core means that your glutes can help keep your knees in proper alignment when you run, preventing knee and ankle pain. It means your back has the endurance to maintain good posture even as you fatigue on longer runs so you can sustain pace and form. A strong core also allows your hips to remain level with each footfall, reducing force down the leg and, therefore, helping to decrease the risk of overuse injuries.

Going back to basic movement patterns, focusing on bodyweight only, is an outstanding way to build the mind-body connection and increase core strength. Bodyweight exercises provide plenty of resistance to challenge key muscles. Although, as noted in the gear guide below, I’m a fan of adding resistance bands to increase intensity.

Ideally, your training plan Your core needs strength sessions per week—every exercise will engage the core somewhat—and up to two additional core-focused sessions. But schedules are rarely ideal, so even 10 minutes of core work done consistently will have benefits.

Adding moves to your existing warmup stimulates your muscles so they work more efficiently throughout your run. It also means you’re less likely to skip the core work when your to-do list is already overloaded.

When first adding core workouts Strength Training Boosts Performance, Study Says Runners World; Getty Images for 30 seconds or complete 10 reps of a movement. That’s normal and simply a reminder to stay consistent. Focus on mastering the basic movements, and you’ll build more power than if you progress without making the connection between the exercise and the muscles you should feel firing during that move.

After just a couple weeks of core exercises, most runners notice increased stability in their stride and less deterioration of their running form as they fatigue. And those changes make it easier to stay as committed to your core as you are to your daily runs.
