Eating carbs before exercise fuels your training and helps with recovery. It’s a popular misconception that you only need carbs if you’re engaging in a long (more than two hour) bout of endurance exercise.

So, unless you’re just going for a quiet stroll, ensuring that you have some carbs in your system will improve high intensity performance.
