People who exercise regularly are more likely to drink moderately. Drinking and training go hand in hand.
Decades ago, it was commonplace to see weight trainers sipping on beer during their sessions in the gym. In fact, gyms were often located in the back of a bar.
Today there is a correlation between alcohol consumption and training. The reasons vary from social outlets to being bombarded with alcohol commercials during sporting events.
Most studies show that that who exercise are 2x as likely to consume alcohol versus those that do not train. As long as the consumption is moderate, there generally is not a problem.
