Caffeine consumption can positively impact workout performance by increasing energy levels and enhancing endurance. It acts as a stimulant, improving focus and reaction times while reducing the perception of effort, making workouts feel less strenuous. Studies have shown that caffeine can delay fatigue, allowing individuals to train harder and longer. Additionally, it may promote fat oxidation, potentially leading to weight loss and improved body composition. However, moderation is key, as excessive intake may lead to negative side effects such as anxiety or heart palpitations.
