I did this core workout the other day. And I felt it the next two days. So I would say it works. I'll be adding it to my core workout rotation!
I have learned to appreciate the importance of a strong core since I began running. As I've continued to educate myself about muscle imbalance, proper mechanics, injury prevention (the recent fail excluded), etc., one thing is a constant: the emphasis on a strong core.
For a long time, my focus was on just my abs and my end goal was a six pack. I reached my goal. I have a six pack. You just can't see it. It has a little layer of padding covering it, but it's there. If you press hard enough, you can feel it. Which is good because those muscles are so important to staying injury free and being a strong runner. But not just those muscles. The core also includes your hips, glutes and back muscles!
Weak abs affect the way you run - how long or short your stride is and how your hips move. If your stride is too long or too short, it can lead to injury. If your hips are tight or weak, you can also become injured. If the muscles are weak and not moving the way they are designed to move, the muscle can get inflamed or even torn or other muscles have to compensate and you end up with injuries from overuse.
Put even more clearly:
Your core is the foundation of the running movement and is essential for speed. The muscles in your abs, lower back and glutes stabilize and balance those of your lower body. This allows these muscles to perform their duties without overcompensating for weaknesses in the lower and middle body. Your core ensures you maintain proper running form during challenges such as hills, sprints or the final leg of long distance runs, supporting tired muscles even when you are fatigued.
Here are some other ab workouts I like:
And of course...
How often do you work your core?
What is your favorite core exercise or workout? I'm always looking for new ones to keep things interesting!
