Ewww. Not Core Exercises.

Yes, core exercises! According to the Mayo Clinic, "Weak core muscles can lead to more fatigue, less endurance, and injuries." This especially comes into play at the end of a race when your body is tired. With a strong core, you can maintain stability, proper form, and breathe more easily, even when you're fatigued. So... remember to include 5-10 minutes of core work in your daily routine!
