Non-stimulant Pre-Workout

Non-stimulant pre-workouts, moslty known as non-stim, do not contain caffeine and are a good alternative to normal pre-workout for people who are sensitive to caffeine or who usually exercise at night only a few hours before bedtime. 

Although this pre-workout type does not contain any caffeine, it has many of the same effects and benefits as a stimulant pre-workout has. Non-stim pre-workouts often contain nitrosigine and beta alanine, which increase the blood flow, bringing more nutrients and oxygen to the body, improving energy and performance.
