Difficulty: Moderately Easy
Step1
Go straight the source. Check out your local gym's website or the YMCA website for descriptions of classes offered. Here you will learn that spinning is a cardio workout involving a stationary bike. Although twirling around in circles is probably more fun, classes like this have become very popular since they are such a great way to burn calories without getting bored.
Step2
Tag along with a friend. Ask a friend if her gym offers guest passes. Go along with her for an aerobics class or just to work out on the cardio and weight equipment. Having someone you are comfortable with show you how to use the equipment or do the moves will make it easier to pick up on words like "reps," "sets," "road run" and "grapevine."
Step3
Have a good sense of humor. If your kick-boxing instructor calls out to "jab, cross, hook, upper, pop, pop and duck," and at this point you can't tell the difference between your foot and the back of your hand, just laugh it up. These things are confusing to everyone at first and, chances are, everyone in the class is messing it up. The point of these classes isn't to become an expert on the lingo and the moves, but just to keep moving and burning calories. No one cares if you hook instead of upper.
Step4
Ask questions. The gym can be very intimidating, especially if you haven't set foot in one since leg warmers and leotards were all the rage. Ask the staff when you aren't sure about how to do something properly. If someone asks you if they can "work in," just let them know you have no idea what they mean. To "work in" means to alternate with someone on a piece of equipment so they can get their set in while you rest. Additionally, don't be offended if you see signs telling you to strip when you're finished with the weights. This is just a reminder to remove the weights from the machines and put them back on the rack.
