User: Why do people work out at the gym?
Assistant: People work out at the gym for a number of reasons: to lose weight, stay healthy, body building competitions, learning about fitness, becoming a trainer, group fit classes, and fitness socializing / friendship.  The most common reason is most likely weight loss.  Getting in a gym for this reason is a great way to stay motivated because you see people around you who are also doing the same thing as you to lose weight.  This community of people will be able to give you the support system needed to be successful in a short or long term weight loss journey too.
