Caffeine is proven to improve sports performance. It can be used before (caffeine loading) or during exercise to improve both mental and physical performance. Use caffeine correctly to reduce your perceived exertion and increase your endurance performance. Check out the High5 nutrition guides to find the correct dose of caffeine for your bodyweight. Caffeine does not add to dehydration during exercise.
