Many 
of us have heard for a long time that caffeine may be able to help us perform better. Studies in fact prove that caffeine before a workout or an endurance activity will enhance performance. It has been theorized that Caffeine increases fat metabolism. The result is in an increase the number of fatty acids circulating in the bloodstream enabling people to run, swim, or bike longer. The body can absorb and burn that fat for fuel and save the body’s limited stores of carbohydrates until later in the workout.
Caffeine also enhances mood and gives us that jolt of energy that we sometimes need. As far as lifting goes beside the energy boost it also “antagonizes adenosine,” a substance in muscles that builds up during exercise and reduces the force of muscular contractions. The more adenosine in a muscle, the less force it generates. Caffeine reduces adenosine levels, “which then enables more forceful muscular contractions and delays fatigue,” Dr. Duncan says. (Michael Duncan, a senior lecturer in sports science at the University of Exeter in England.)
This is NOT to say you should have 800 mg of Caffeine a day. Keep in mind that Caffeine also has negative side effects when taken in excess. Like anything we can build a tolerance to it and once we come off caffeine we will even have withdrawals. Withdrawals are typically lack of energy and headaches. So go ahead and have some caffeine in the morning or before your workout, but remember 3 pots of coffee a day may not be the best thing for you. Standard dosage of caffeine tends to be around 100-200 mg.
