We all love caffeine, well most of us do anyway, and it’s got to the point where almost every pre-workout supplement out there is made up of mostly caffeine in ever-increasing amounts. We’ve talked about a lot of these in our article on the best 10 pre-workout supplements. But not everyone can consume caffeine, finding a pre-workout supplement that is stimulant free is the only option for them.
Also, even you caffeine lovers should contemplate a stim-free pre-workout every once in a while. While caffeine is amazing, you can fast build a tolerance meaning that all of the benefits that you enjoyed (increased power, increased energy, less fatigue, and lowered rate of perceived effort) can vanish!
You can also begin to experience some negative side-effects such as increased cortisol, troubled sleep, and even weight gain. If you are beginning to suffer the effects of too much caffeine, then a stimulant free pre-workout (combined with a caffeine-free diet) can help to lower your tolerance levels while also providing you the energy required to smash your workout. In this article, we are going to look at 10 of the best stimulant free pre-workouts available to you.
