Coffee Is the Best Pre-Workout

Caffeine is one of the most thoroughly studied performance enhancers available. It increases strength, endurance, focus, and pain tolerance, all measurable, all replicable, all at doses that are safe for most adults. Three to six milligrams per kilogram of bodyweight, taken thirty to sixty minutes before training, is the dose-response sweet spot.

The best delivery system in most cases is plain coffee or espresso. It is cheaper than any branded pre-workout, has a centuries-long safety record, and lacks the proprietary blends that make pre-workout dosing a guessing game. A double espresso provides roughly one hundred and fifty milligrams. Two cups of strong drip coffee provides around three hundred.

The trade-off is tolerance. Daily heavy use blunts the performance effect. The strongest results come from cycling, using caffeine for hard sessions and skipping it on easy days. Avoid intake within six to eight hours of bedtime. Sleep is still the single largest performance variable, and caffeine eats it from the back end.
