Definition
Pre-workout supplements without stimulants like caffeine, for people who want focus without the jitters, heart palpitations, or 3 AM wakefulness. Decaf for gym rats.
Example Usage
I switched to stim-free pre-workout after the regular version made me feel like I could bench press a car but also might spontaneously combust.
Origin
Emerged as supplement companies diversified products in the 2010s for caffeine-sensitive consumers
Fun Fact
Stim-free pre-workouts rely on ingredients like citrulline and beta-alanine for performance, proving you don't need to vibrate at hummingbird frequency to lift heavy.
