The words ‘pre-workout’ and ‘caffeine’ practically go hand-in-hand. But if you work out late at night or are sensitive to stimulants, the last thing you need is a high-stim pre-workout—unless, of course, you dig the jitters or staring at the ceiling all night.
Skipping the caffeine doesn’t mean you’re stuck going into workouts with a shaker cup full of plain water. A stim-free pre-workout can give your muscles (and mind) the edge needed for you to rip through a killer workout. Check out the following six popular picks for the pumps, endurance, and determination you’re after—all without a milligram of caffeine.
1. GAT Sport Stim-Free PMP
