My Favorite Fitness Activity

In my quest for a healthy lifestyle, I've explored various sports, but running stands out as my favorite. It's a simple yet effective way to keep my body in shape and mind at ease. I run three times a week, often accompanied by classmates, chatting and sharing our fitness journey. The transition from burning sugars to fat occurs after about 20 minutes of moderate exercise, making it a sustainable choice. Running not only enhances my physical fitness but also serves as a great stress reliever, helping me stay focused and energetic throughout the day.
