Core Workout For Runners

Core Workout For Runners

Sharing a core workout for my runner friends out there.

Hi friends! How are you? I hope you’re having a lovely morning. I’m looking forward to a strength workout, some time on my PEMF mat with my red light mask, and then an afternoon full of client calls.

In today’s post, I wanted to share some tips on core work for runners.

The reality is that running can feel like a complete workout on its own: it builds endurance, strengthens the cardiovascular system, and challenges the lower body. But if you want to take your performance, posture, and resilience to the next level, what you do when you’re not running matters a LOT, too. How’s your mobility? Nutrition? Sleep? Recovery? Core?

Working your core muscles can improve balance, efficiency, and reduce injury risk. The core is more than just your abs, It also includes your hips, lower back, and glutes, which play a huge role in running form and power.

Today, I’m sharing a round-up of the best core workout for runners so you can add simple, effective moves to your strength training routine. These exercises don’t take long but offer huge benefits for every type of runner, whether you’re training for your first 5K or figuring out how to train for a half marathon.

Core Workout For Runners

Today I wanted to chat about:

Why a strong core is crucial for runners.

The benefits of consistent core training.

A detailed list of the best core exercises with how-to steps.

Guidance on how often to include a core routine in your training plan.

My goal is to make this guide as practical and easy to implement as possible. Bookmark it, save the exercises, and I hope it can provide some inspo for your next training cycle!

Is A Strong Core Important For Runners?

Yes x 1000000000. Many runners neglect core strength because they assume running itself is enough. But a weak core can lead to poor posture, reduced efficiency, and even injuries.

A strong core helps you maintain proper alignment, keeps your pelvis stable, and reduces unnecessary side-to-side movement. It also allows you to transfer power more efficiently from your upper body to your legs, helping you run faster and farther with less effort.

(flash back to when I used to run regularly! I’m starting to ease my way back into some sprints!)

Why Do Runners Need A Strong Core

Improved Running Economy

When you engage your core during a run, you stay in a more straight line and avoid wasting energy. This efficiency can improve endurance and helps you maintain pace over long distances.

Reduced Injury Risk

Weak core muscles can contribute to overuse injuries in the hips, knees, and lower back. A strong core supports stability so each stride is smoother and safer.

Better Posture & Breathing

A stable trunk helps runners keep their shoulders relaxed, ribs down, and chest open – all of which make it easier to breathe efficiently and prevent slouching as fatigue sets in.

Power & Speed Gains

By creating a strong base, your body can transfer more power with each stride. Think of it like a bridge: the stronger it is, the more weight it can carry. Runners with solid core strength often notice better sprint finishes and uphill power.

What Are The Best Core Exercises For Runners

Here’s a core routine you can rotate into your training. Aim for 8–12 reps per side or 30–60 seconds per exercise.

Plank Position

Get into a straight line from head to heels, with elbows under shoulders.

Keep your arms straight or bent, and focus on keeping your feet flat.

Hold and engage your core to avoid sagging hips.

Side Plank

Lie on one side, legs stacked, and lift into a side plank.

Keep hips high, body in a straight line, and don’t forget to switch sides.

Add a leg lift for extra challenge.

Functional Fitness Workouts You Can Do at Home

Dead Bug

Lie on your back, arms straight up toward the ceiling, knees bent at 90°.

Lower one arm and the opposite leg while keeping your low back pressed down.

Return to start and switch sides.

Bicycle Crunch

Lie on your back with feet flat lifted.

Extend one leg while bringing the opposite elbow toward your bent knee.

Move in a controlled side to side motion.

Glute Bridge

Lie on your back, feet flat, knees bent.

Press into heels, lift hips, and hold.

Add a single leg variation for runners to challenge stability.

Resistance Band Rotations

Anchor resistance bands at chest height.

Stand tall, hold with both hands, and rotate side to side keeping hips stable.

This mimics running’s rotational control.

How Often Should Runners Do Core Work?

Most runners benefit from adding core exercises 2–3 times per week. You can tack a short core routine onto the end of a run or dedicate a quick 10–15 minutes on strength training days.

The key is consistency. Over time, you’ll notice better stability, less fatigue, and stronger running form.

Running is about so much more than strong legs and good shoes. By training your core muscles, you’ll build a foundation that supports every stride, reduces injury risk, and helps you run more efficiently.

Try this core workout for runners consistently and notice how much easier it becomes to hold posture, breathe deeply, and keep powering through those long runs.

And if you want to dive deeper into developing a well-rounded strength program, here’s a great place to start: functional core training.

I’d love to hear from you in the comments: How often do you do core work as part of your training? Do you have a favorite move?

Discover The World’s Smallest “Mountain” – The Mount Paltry

Discover The World’s Smallest “Mountain” – The Mount Paltry Move over Everest, there’s a new headline-grabber in town and it’s barely taller than you are. Mount Paltry has exploded on social media as the world’s smallest mountain , a tiny bump in Australia that has become internet-famous precisely because it looks… well, not very mountain-like at all. In a world obsessed with extreme hikes and record-breaking peaks, this modest mound has captured global attention by doing the exact opposite: being proudly underwhelming. Where on Earth Is Mount Paltry? Mount Paltry is described in viral posts as a miniature mountain in Australia, rising only a few metres above the surrounding land. It’s usually shown as a small, rounded rise in an otherwise flat landscape the kind of bump you might expect to call a hill, or even “just a bit of ground,” rather than a mountain. That’s exactly why people love it: the contrast between the dramatic title “world’s smallest mountain” and the very ordinar...

Glamorous Plus-Size Wedding Guest Dresses in Beautiful Styles

Glamorous Plus-Size Wedding Guest Dresses in Beautiful Styles Did you know that over 67% of women in the U.S. wear a size 14 or larger? Yet, despite the demand, the fashion industry has been slow to provide elegant, well-fitting, and on-trend plus- size wedding guest dresses. Many women face limited choices, ill-fitting designs, and outdated silhouettes that fail to highlight their curves. Shopping for the perfect dress can feel like navigating a minefield either the options lack style, the fit is off, or the available dresses don’t align with the formality of the event. For years, plus-size women have been told to “hide” their curves instead of celebrating them. Traditional formalwear often lacks the structure, comfort, or aesthetic appeal needed to make plus-size wedding guests feel just as glamorous as their straight-size counterparts. The frustration of sifting through uninspiring racks, struggling with restrictive fabrics, or settling for ill- proportioned designs is all too fami...
