Coffee can be a great pre-workout beverage, as caffeine boosts energy levels, focus,
and endurance. Studies show that caffeine can enhance athletic performance by
delaying fatigue and increasing alertness. For optimal results, drink coffee about 30
minutes before exercise to give the caffeine time to take effect. Avoid added sugars,
and stick to black coffee or espresso to keep your drink calorie-free. Just remember to
stay hydrated, as caffeine has a mild diuretic effect. A simple cup of coffee can give you
the edge needed to make the most of your workout.
