Crashing your workouts every time you step in the gym is not as easy as it sounds. There will always be those days when you are not in it, either mentally or physically. This is why many people rely on pre-workout supplements to keep their energy, power, and overall motivation high at all times. Most of these supplements use stimulants, which is totally understandable because they are clinically proven to be very effective at boosting energy and concentration.
Sadly, they also have some downsides like jitters, stomach upset, headaches, and mood swings. Stimulants can also cause insomnia, especially when taken close to sleeping hours. The simple solution here is to go for caffeine-free pre-workout supplements. However, you can't just pick any stim-free pre-workout and expect great results. That's because a majority of the caffeine-free pre-workout supplements don't work.
So, what are the best caffeine-free pre-workout supplements, and how do they work?
