Caffeine has been used effectively for decades as a pre-workout. This natural substance has been extensively researched and works by stimulating the central nervous system. It is a performance enhancer and has profound effects on your body’s response to exercise. Caffeine is rapidly absorbed in the body and starts to kick in after about 40 minutes. It is slow to breakdown so its effects last a long time, making it particularly good for increasing endurance, so you can exercise with maximum output for longer periods of time.
Caffeine has been shown to improve performance for endurance sports like cycling and running as well as stop-go sports, such as football. It enhances cognitive ability and improves your score where precision and accuracy are needed e.g golf. Anaerobic high-intensity workouts such as weight lifting and sprinting are also significantly improved with caffeine taken pre-workout.
