Pre-workout is designed to boost energy, enhance focus, and improve performance during high-intensity exercises by providing stimulants like caffeine and performance-enhancing ingredients. It's not necessary for low-intensity workouts, as proper nutrition and hydration are typically sufficient for those sessions. Different people have different expectations from a preworkout though, some people like it to boost endurance and opt for a preworkout with something like peak02, others like a lot of stims and will go for something with heavy amounts of caffeine and other stimulants while some are seeking a preworkout with thermogenic ingredients that will make them sweat like grains of paradise so everyone is looking for something a little different out of their preworkout
