A stable core is a game-changer for any runner. According to experts, it’s the secret to enhancing your performance, reducing lower back pain, and even preventing common running injuries.

And let’s face it, that’s great news because a recent survey of 4,621 runners showed that a whopping 30% of them had suffered from a running-related injury in the past year.

Injuries are tricky to pinpoint, but experts agree that core stability exercises can help keep you in the game. So whether you’re a beginner or a seasoned pro, building a strong core is essential.

Running is an amazing exercise that can bring countless benefits to your body, from boosting cardiovascular endurance to increasing bone density and overall strength.

But unfortunately, running can also take a toll on your body, causing knee and hip pain and other issues. The good news is that there are specific exercises you can do to strengthen your core and lower body, improving your running times and reducing your risk of injury.

In this article, we’ll share with you some of the best core exercises that are scientifically proven to strengthen the rectus abdominis muscle, as well as other muscles of the core. So get ready to take your running to the next level and stay injury-free!

The exercises we’ll explore here are based on a list created by The American Council on Exercise in 2001. The study ranks the best and worst exercises for strengthening the rectus abdominis muscle. The exercises are ranked according to how much rectus abdominis gets activated by the movement.

Remember to also incorporate exercises for the obliques and other core muscles to ensure your entire trunk muscles gain strength.

Please note that due to the unavailability of pictures and descriptions of the exercises from the study online, some of the exercises mentioned here may not match the exact descriptions given in the original study.
