Pre-workout pumps have one basic effect: to energize you and "force" you to lift heavy weights in the gym. Most pre-workout supplements do this with stimulants that increase blood flow, heart rate, energy and focus. This makes one feel that he can train harder and with greater intensity in order to get more out of his training or perhaps overtake his sparring partner on a bench press. The most common ingredients in today's popular pre-workout supplements include caffeine, beta-alanine, leucine, and nitric oxide promoters, such as arginine or citrulline, all of which help increase blood flow and "pumping" during training. However, nutritional supplements are constantly evolving and companies have begun to add various other natural stimulants to today's pre-workout pumps, such as guarana and green tea extract.
