workout
You’ll have to do more than just running if you want that all important PB this year. Your core connects your upper and lower body to work as a unit while you run. Improving the strength of all the muscles in your trunk will improve your posture and make your running stride more efficient. It will also increase the power of your push off, making your strides more effective. A strong core improves your balance, which reduces energy loss; this will help you to run faster.
