Carbohydrates should make up around 45-65% of your daily diet. They are your body’s preferred source 
of fuel during exercise and your brain’s number one fuel source during the day, which is why many people often feel fatigued or lightheaded when they have not eaten for a period of time. Because of this, we should make sure to properly fuel up approximately 1 hour pre-workout with a small snack or meal containing carbohydrates that is easily digestible. Aim for a snack with 5 to 15 grams of protein and 15 to 30 grams of carbs. Try these 2 pre-workout options:
Option 1
1/2 Banana plus a handful of blueberries
Option 2
Smoothie
1/2 scoop chocolate protein powder
1 fist spinach
1 banana
1 thumb peanut butter
8 oz. chocolate, unsweetened almond milk
