If you like to run then you need to work on your core. But many runners don't bother. They get caught up with their sport and run all the time. While this does help their time a bit it won't make them markedly faster.
If you want to run, and run well, you need a strong core. All of your power comes from your core no matter what type of athlete you are. And with runners it's very important.
This is because runners with weak cores tend lean forward as they run. When they do that they can't take deep breaths since their stomach is crunched down. Of course they get more tired since they are not breathing well, go slower and don't get as good a workout.
But working on your core will make you a much better runner in no time. I'm not talking about doing hundreds of crunches either. Planks, crunches, situps, mountain climbers all should be part of a runner's core training. In this way they get stronger and hit their core from many different angles.
If you're a runner try to do some core work. You don't need hours of it. two to three workouts on your core of 15 minutes a time will do the trick. You'll watch your times drop and you'll feel less tired even as you run farther and faster.
