If you eat before working out and don’t do more than 10 sets per muscle group, your muscles won’t run out of sugar.

Typical resistance training sessions deplete muscle glycogen by no more than 40%, even under high-volume conditions.

People who don’t lift weights regularly burn more sugar from their muscles during a workout than people who lift regularly.

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.

The more sets you do when lifting weights, the more sugar your muscles burn through.
