Let's face it, there are a million different gyms out there today and all of them are a little bit different. You have your Curves for the ladies, you have the Powerhouses for the powerlifters, you have the Gold's for the bodybuilders, and so on and so forth.
Finding one you feel comfortable with is key. If you join a gym where you are uncomfortable or intimidated, you will more than likely quit and give up. Therefore it is important to really feel at home with whatever gym you choose.
