Based on what i seen , i think anyone who is JUST starting to go the gym should NOT be using a pre workout. The reason being is because you should spend a few months or maybe a year trying to get yourself used to working out WITHOUT them. You should be able to go to the gym and naturally get yourself intense, amped, and super focused. They should only be used by inermediate, advanced, or pros. Eventually, you are going to have to cycle off of them to rest up your nerves and hormones. ( I took them straight for 7 months, dumbest thing i ever did, but im been off them for 2 months lol)
I have seen a lot of guys and girls have really bad workouts because they became too dependent on pre workouts and they never took the time to get used to working out WITHOUT them. I even seen some people skip days because they didnt have their pre workouts. I know none of this stuff might be scentifically proven, but its something i feel like i can share with you. I no longer use pre workouts and I am still able to have THE BEST workouts ever.
In conclusion, Im not saying not to use them. They deffinitly make an impact and will give the energy you need to have good workouts, but just hold off and naturally get yourself focued, amped, and ready to tear it up.
