One slice of this bread should do the trick before you go off to the gym or outdoors. Once you have it made, grabbing a slice is much easier than slathering peanut butter on toast and slicing bananas on top, which is another great pre-workout snack or meal. You could bring a slice with you to work and save it for just before you leave for the gym. Or scarf it in the morning, preferably 30 minutes to an hour before exercise.
