Pre-workouts can be divided into two groups: those with stimulants, and those without. The stimulants pretty much always include caffeine, in widely varying doses, but may include other stimulants including yohimbine, theacrine (Teacrine as the most common), guarana, and many others. Many supplement companies have developed stimulant-free pre-workouts for those who are sensitive to caffeine, simply don't want it, or who exercise close to bedtime.
If you're looking for a pre-workout that will make you feel amped up and ready for action, you'll find no shortage of them out there. However, if that's exactly what you don't want, you still have choices. And many pre-workouts fall in the middle, with no more caffeine than a cup of tea or coffee.
