Eating carbs before a normal weight workout doesn’t make you stronger or let you do more reps, unless you’re training super hard with lots of sets or haven’t eaten all day.

Eating carbs before or during a normal weightlifting session doesn't make you stronger or let you lift more reps, as long as you've eaten recently and aren't doing super long workouts.

If you’re doing a ton of sets for one muscle group (like 12+ sets of squats) or training twice in one day, eating more carbs might help you push harder — otherwise, it doesn’t matter much.

Even after a really tough weightlifting session, your muscles don’t run out of fuel fast enough to slow you down, and they can refill just fine even if you don’t eat carbs for a while.

If you're doing a really long, intense workout or two hard sessions in one day, eating carbs might help you lift more—but only if you were hungry or hadn't eaten, not if you're eating the same number of calories from other foods.

Eating a lot of carbs for a few days before a workout won’t make you stronger — even if you eat way more calories than usual. Your body can refill its energy stores just fine without extra carbs.
