9 Must Do Core Workout Exercises for Runners

Core workouts for runners are more than just a once in a while workout program; it’s movements that can improve running performance and also reduce the risk of injuries. Core workouts help stabilize your body while you run and so much more.

Unfortunately, runners often overlook core exercises because there’s a general lack of knowledge and understanding about how important they are.

Other times, many runners just aren’t sure what are the best core exercises they can do even as beginners.

If you’ve had some (or all) of these questions pop into your mind from time to time, this is the article for you. As a running coach, I’ll share not only why you should focus on core exercises but also which ones are the best core exercises for runners.

One of the most common reasons for running injuries is a weak core, which is to say our hips, glutes, lower back and abs. A runner core workout is about so much more than a six pack, it’s important to understand this and create a program that works.

In fact, a Canadian study over 13 years and 8,000 people showed a death rate more than double for people with a weak mid-section! Holy smokes, we absolutely need some runner core workouts, right?!

This is a HUGE focus for me and I’m excited to help you understand why it matters for running.

• Core and abs are not the same thing.
• A strong core means better endurance, better strength and a pain free back.
• A strong core also means better posture, which can instantly make you look leaner.

Why Do Runners Need a Strong Core?

When you think of a strong core, many times the first thing that pops into your mind is probably having a six-pack. But core strength is more than just that.

Having a strong core serves two main purposes for runners: improving performance, and reducing injuries.

To understand this further, we need to look at what function our core muscles serve. They are what control our torso and stabilize it. Our core muscles are what keep our torso upright when we run and reduce unnecessary movement when we’re engaging our arms and legs during a run.

This type of core strength helps our pelvis, hips, and lower back stay strong and work together to help us move more efficiently and to expend less energy. It naturally allows us to have good posture and assists us in achieving the proper form when running.

All of this combined can drastically improve running performance over time.

When it comes to injury prevention, having a strong core will reduce the risk of common running injuries including:

• runner’s knee (patellofemoral syndrome)
• IT band syndrome
• plantar fasciitis
• shin splints
• even stress fractures

What Muscles Make Up Your Core?

As I mentioned above, when we think of our core we often envision six-pack abs, but core and abs are not the same thing. Our core includes our abs but it is much more than that.

Your core muscles refer to different groups of muscles that are located within your abdomen or the ‘trunk’ of your body. There are 35 different muscles in your core and can be broken down into 8 major groups:

1. Rectus Abdominis

These are the muscles that make up your six-pack abs. You can work these through crunches, sit-ups, and really most any traditional ab moves. They help to contract the body to curl the upper body down or lower body up and help to raise your legs.

2. Transverse Abdominis

These muscles lie at the back of your rectus abdominis and around the body to the lower spine and are a major stabilizer when you run.

You can work this through planks, Pilates, stability ball moves, etc. They help to improve breathing for your runs too!

3. Obliques

This includes both your internal obliques as well as your external obliques and provides stability to your sides and the front core. The external ones are ab muscles that run along your sides, and the internal ones help twist your body from side to side.

They help to keep your shoulders square and help you breathe better while running. A sign of oblique weakness is that people stop breathing when performing simple movement patterns to maintain stability.

You can work these with bicycle crunches, side planks, and the moves below!

4. Erector Spinae

These are a group of muscles that are located around your spine all the way from the cervical to lumbar areas, in other words from your neck down to your lower back area. They make up your lower back muscles, allow you to have a stable spine, and support your core when it’s engaged.

You can work these through lying on your stomach and doing supermans, deadlifts, etc. Having a weak lower back won’t support those strong abdominal muscles, so they all go hand in hand.

5. Multifidus

They are a group of muscles that wraps around either side of your spine from your pelvis to your neck. It contributes to the stability and support of the entire vertebral column, particularly in the lumbar region, and is most associated with lower back pain.

6. Diaphragm

Your diaphragm is part of the core muscle group that’s right beneath the ribs and helps you properly breathe in and out during a run.

7. Pelvic Floor

These are the muscles located between the tailbone and the public bone between the pelvis. They are often ignored and can be even more important for those of us running postpartum.

8. Glutes

Last but not least we have our glute muscles, which we all know aren’t just one muscle but three different ones. They help stabilize our core and even absorb some of the force when running to reduce the risk of knee injuries.

You can work these through squats, lunges, running, etc. They help to provide power to your stride, keep your gait aligned, and ensure your hip flexors aren’t overworked.

All right now we know it’s important, let’s learn what it does and then work it!

How Often Should Runners Do Core Workouts?

A lot. And far more than you’re probably doing!

In fact, as a running coach, I recommend doing it prior to every single run. But that means that the best core exercises will be a combination of different ones so you can mix and match.

But what’s also important is to know how to get into the proper form when doing them so that they benefit you rather than lead to an avoidable injury.

After many of the runners I worked with asked for one, I developed the 30 Day Runner Core Program! It’ll guide you through 10 minutes a day which will make all your runs better.

So, if after you’ve gone through the exercises below and want to really dive into your core training and built strength, this is a great program that’s designed for runners and will give you everything you need to perform at your best.

Because, unfortunately, as much as I love planks and they work great (more on that down below), a plank a day won’t make you a better runner or hit all the key muscles

Should I Do Core Exercises Before or After Running?

Doing core work before or after running is often a personal choice.

But here’s a breakdown of reasons why doing it around your workout is key and how it affects you before vs after your run:

• Prior to your workout it activates muscles,
• Muscle activation means they are ready to work and provide more power
• Prior to a workout means it’s part of your dynamic warm-up and you’re less likely to skip it
• Too much prior to a workout can over-fatigue the muscles, in which case why not do half before and half after
• Post-workout has fewer benefits on that run but will benefit you overall

What does running do for your core?

Running can help to improve the endurance our core muscles, but the truth is we need to be doing external work to truly get the benefits we’re looking for.

When running faster, you should notice an automatic tightening of your core. This also happens because you are slightly leaning forward and therefore it’s maintaining your balance. Some runners have said this along gave them a six pack, but for most of us that won’t be the case.

Best Core Exercises for Runners

Now that we’ve covered why runners should focus on core exercises, as well as when to do them, let’s look at my pick of some of the best core exercises for runners that you can try today. You don’t need crazy wild super complicated movements. In fact, we want ones that we can truly feel and progress by adding bands or over time start to mimic muscles we’d like to activate during the run.

Perform 2 rounds with 10 reps of each move below:

1. Plank with Leg Raise

A plank is a great exercise to start with and covers most of your core muscles. They’re especially great for runners since they focus on the engagement between your core and limbs.  But I don’t like a static plank because running isn’t stationary!!

To do this, lie flat on your front and then lift up to the top of a push up, with your shoulders stacked over your wrists. Make sure you have a flat back and hold your body in a straight line from your ankles through your trunk and to your shoulders. This is the proper form for a plank position.

Now while squeezing your glutes and abs, alternating raising and lowering the right leg and then left leg just a few inches. The goal is not to let your hips dip when raising the leg.

A plank is more about the time you hold it. For a less challenging position, you can drop to your forearms till you built up your strength.

2. Knee to Elbows High Plank (Cross Body Mountain Climbers)

A variation of the classic plank position is the knee to elbows high plank. To do this, start in a full plank position and keep your abs engaged.

Then, lift your left knee and bring it forward towards your left elbow. Go back to the starting position and switch sides by now bringing the right knee to the right elbow.

Make this a slow and controlled movement, really focusing on the squeeze of your abdominals.

3. Glute Bridge March

There are a lot of glute bridge variations and learning to get in to proper position will maximize your time using them. This is one of my favorites because you’ll absolutely feel the muscles working.

Lie face up with arms extended along the body, so finger tips are touching the back of your heels.

Press full foot in to ground to raise hips up to a straight line with head. Then slowly alternate picking up the right, then left foot a few inches. As always, don’t let the hips sway or drop.

4. Deadbug

A great movement to find core weaknesses!

Lying on your back with arms straight above and knees bent to 90 degrees (think table top position). You should not have an arch in your back.

Option 1: Try to simply hold this for 2 minutes and see if you fatigue and start arching

Option 2: Keeping the right arm straight, lower it along side the head, while also straightening and lowering the left leg. This movement requires a lot of control to do it correctly! Most people fly through and miss the benefits.

Return to starting and do the opposite side.

5. Walkouts

From a standing position, roll down as though going to touch your toes. If you need to bend your knees that’s ok!

Place your hands on the ground and walk them forward to a full plank position. Engage the core and do a pushup.

Then slowly walk the hands back to your feet, keeping the legs as straight as possible. This is going to work on that hamstring flexiblity, which many runners are lacking.

Once hands are at the feet, slowly roll back up to standing. A stellar full body movement!

6. Fire Hydrants

Yet another move that everyone in my 30 Day Core Program is familiar with because it works those hips!

From a tabletop position you are going to raise your bent right knee to the side, just like you might imagine a dog peeing on a fire hydrant. It’s a slow and controlled movement.

Once you’re not letting your body tilt or sway with the movement, you can add a band above the knees for additional resistance.

7. Side Plank

This movement really works the glute medius (along with the obliques), which is a very under activated muscle. Yet of course is part of those powerhouse glutes!

Getting in to a forearm side plank, press the bottom foot in to the ground. This is press is key!!

Once you feel stable begin to raise and lower the top leg. This is going to require more focus on keeping your hips strong and high so they don’t sag during the movement.

8. Advanced Russian Twist

This is a useful core exercise, but often done incorrectly which can lead to back pain. SO only add this in if you definitely have the form correct.

Start by sitting on a mat with your knees bent at a 90-degree angle.

Root into your sit bones as you lift your feet up from the floor. Keep your knees bent while you do this. Make sure your core is engaged and your torso is upright to create a V shape with your thighs and torso.

Now extend your arms out in front of you and interlace or clasp your hands together. Using your abdominal muscles, twist to the right and then back to the center, and repeat it on the left side. That’s one rep.

To take it up a notch, you can hold a light dumbbell in your hands as you twist from side to side.

9. Better than a Superman – Low Back Pull

Your back plays a key role in holding good posture while you run, so let’s not leave it out of our core exercises.

Lying on your stomach with arms and legs extended. Contract the core and raise both arms and legs, then pull arms down as though doing a lat pull. Arms are bent to field goal posts then straightened and you lower back down.

Raising the legs helps engage that lower back, which often gets sore in newer runners.

Yup, it’s a number of basic movements.

You don’t need crazy wild super complicated movements. In fact, we want ones that we can truly feel and progress by adding bands or over time start to mimic muscles we’d like to activate during the run.

Here are a number of additional free workouts, but honestly if you want to truly see gains. You need a program that you’ll follow and do consistently!
