Pros
Free membership, low formality culture at corporate office, fun people (most of the time). Great place to get a ton of experience because they run a LEAN team. Fast paced culture means you'll never get bored. Great place to learn as much as you want about your personal health and fitness with tons of great and knowledgeable people!
Cons
No work/life balance or respect for employees. When you meet a goal, all they expect is more. It never seems to be good enough. Feels like a "boys club" a lot of the time with senior management... you really feel the glass ceiling here. I feel like i'm always connected to work- at home I feel like i have to check my email at all hours in case a senior leader needs something. At times it feels like i'm working with jr-high age people. If you don't like profanity, you may get easily offended.
