Better communication and not putting up with poor management practices.
More professional management staff. Better in-club marketing for special events. An editor/proofreader for club communications, educational material, marketing info - sloppy typos are rampant.
Interacting with people who want to live a healthy lifestyle or who want to improve their fitness. I love seeing members set and achieve their goals.
The compensation is fine. I feel undervalued as an employee because I was continually promised time on the schedule, yet was never put on the schedule. I prepared classes only to have my manager refuse to look at what I had prepared.
