Pre Workout supplements can greatly assist in boosting short term energy levels, making it ideal to take before a workout. At the heart of most pre workout supplements is caffeine. Caffeine is a recognised natural stimulant which greatly assists in improving your focus and concentration during your entire workout if taken beforehand. Beta Alanine is also a common ingredient, and is often included in pre workouts due to its ability to protect the body from damage caused by lactic acid accumulation during your workout. It is often attributed to causing a slight to moderate tingling sensation across your body after taking it for the first few times, however it is nothing to fear and your body will adapt to it! Nitric oxide matrixes are also commonly included due to their ability to increase blood flow to the muscles being targeted in a workout, which ultimately leads to better muscle performance and a better workout overall.
