What are pre-workouts?

Pre-workouts are a supplement you take before working out so you can have energy and have an increased performance. It has caffeine, creatine, and other energy and muscle enhancers.

So do they work?

Pre-workouts do have a lot of caffeine, which will give you energy but it won't make you lift more. Pre-workouts aren't necessary to take before a workout. Instead, you should eat a good meal with a lot of carbs. Post workouts are good to take because it will help you recover.
