As far as bodybuilding supplements are concerned, the pre workout supplement is a relative new comer to the workout circuit. There have been many versions of this formula in the past that were taken with the intentions of getting the weightlifter prepared for his workout and to help with muscle strength and endurance. Caffeine, glutamine, and amino acids, where and still are the primary ingredients that assisted in the old school methods of pre workouts.
Today, there are numerous brands of workout supplements that have taken the old school methods and ingredients into over-drive, but no ingredient has had such a huge impact on the industry as NO2 or Nitric Oxide. Nitric Oxide is a vasodilator which when taken in the proper amounts, forces more blood into the muscles which in-turn, provides more nutrients to the muscles both during workouts and after, assisting in recovery.
