Pre-workouts are dietary supplements designed to enhance athletic performance and energy levels during exercise. They typically contain a blend of ingredients such as caffeine, amino acids, and vitamins, which aim to improve focus, endurance, and strength. Many athletes and fitness enthusiasts use these products to help them push through intense workouts. These supplements are usually taken 20 to 30 minutes before exercising. While they can provide a boost, it's important to use them responsibly and be aware of potential side effects, such as increased heart rate or jitters. Always consult with a healthcare professional before starting any new supplement regimen.
