If you haven't really been into fitness before now, the gym can be a very intimidating place. Everyone else looks like they know what they're doing, they all look better than you and you're sure that they can smell whenever new blood enters the room. The truth is, everyone is too busy concentrating on their own workouts that they probably haven't even noticed you worrying about yours. If you need help, then ask for it, or if you find the gym boring and want to learn a new sport, then no one is going to judge you when you're learning the rules.
