If you don't like to exercise or want more energy when you do – or simply want to get in a better workout – then try a cup of coffee. Sure, you've heard it before: Caffeine helps improve athletic performance. But the new evidence in favor of the wonder drug is so overwhelming that if you're not swigging some form of caffeine before your workout, you're doing your body a disservice. Don't believe us? Here are six reasons why you should consider coffee, tea, or Red Bull before, during, and even after your next trip to the gym.
Caffeine fuels your muscles.
If you've ever tried to exercise after having not eaten in a while, you know the results can be disastrous. That's because your body has no ready source of fuel to power working muscles. Yet you don't have to slam a sandwich: Caffeine can also help give your body energy for a workout. "Studies show that caffeine can increase levels of blood fats," allowing your body to use fat instead of carbs for fuel during exercise, says Burke. This lets your body save glycogen stores – your muscles' primary fuel source – for later in your workout when you need them.
