Designed to sharpen focus, boost energy, increase endurance and achieve more satisfying muscle pumps, pre-workouts are among the most popular sports supplements on the market. These products are said to help users improve performance – and achieve better results – in each training session. Pre-workout ingredients vary from one supplement to the next. In particular, some pre-workouts contain caffeine or other stimulants, whereas other “non-stimulant” products are designed for users who wish to avoid any resulting anxiety or energy crashes. Within this category, you will also find a sub-section dedicated to muscle pumps – an effect sought by many gym goers (especially bodybuilders).
