Eating more carbs gives you more energy to lift heavier and work out longer.

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.

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.

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.

After a long workout, drinking a sugary sports drink helps your muscles refill their energy stores much faster than not eating anything at all.
