Did you know that a cup of Joe before workout can actually improve your workout and help you achieve your fitness goals? Coffee is not just a stimulant that helps you beat your lethargies and get ready for a workout session, but it also prolongs and improves the intensity of your workout by building endurance. Caffeine increases the fatty acids in the bloodstream, which in turn, provides additional fuel supply for your muscles to burn fat. This means that you do not have to rely on carbohydrates alone to get an energy boost, you can use coffee as your workout supplement as well.
