If you were going to be left stranded on an island for 1 year and could only take 5 items with you, what would you take? For me, near the top of the list would be CAFFEINE! And why not? Caffeine stimulates the central nervous system so heart rate increases, pupils dilate, muscles tighten, and glucose is released into the blood stream. And caffeine isn't just effective first thing in the morning, it's also a great pre-workout beverage!
Tests show that ingesting between 80 and 300 milligrams of caffeine (between 1 and 3 cups of coffee) before a workout results in longer endurance, faster times, less exertion, less fatigue, and more rapid recovery!
Start with a single cup of coffee or black tea 30 to 60 minutes before your workout to ensure you can tolerate it. Then, adjust accordingly!
