Hold the protein shake - turns out a cup of coffee might be the most effective pre-workout drink you can have.
It's great news for caffeine lovers, who can now get their caffeine hit before hitting the gym.
A new study from the University of Granada in Spain has found that drinking a cup of coffee half an hour before doing aerobic exercise dramatically increases the amount of fat you're burning.
The research also shows that if the exercise is done in the afternoon, the caffeine has more of an effect than in the morning.
