Staff, size, atmosphere, other members I meet and greet in passing. Overall. It's a fun, friendly place; coaches are encouraging and supportive of my efforts and success.
The staff is knowledgeable and does a great job helping you to both understand and navigate the machines. I really love the computer screen, which offers instant feedback regarding your effort and progress! I'm feeling stronger (and thinner!).
I love the philosophy of being able to get a workout in 40 minutes a week. My husband and I have both improved over the 2 years we have been doing it. The staff is positive friendly and supportive.
