Foods known to boost energy levels pre-workout include complex carbohydrates and healthy fats. Options like oatmeal, whole-grain bread, bananas, and nuts provide sustained energy release. Incorporating lean protein, such as yogurt or eggs, can support muscle function. Timing is crucial; eating these foods about 30-60 minutes before exercise enhances performance. Additionally, staying well-hydrated is essential, as water is vital for optimal energy metabolism and overall bodily functions during workouts.
