Pros
If you love fitness the clubs are outstanding, especially the Athletic brand locations. Free membership obviously, great tasting and mostly healthy food choices in the cafe (great coffee!). Daily interactions with the 'regular' members can be the highlight of your day if you like the old health club mentality when people actually socialized. In sales roles you get instant gratification in your paycheck, no yearly bonus. You are 100% commission.
Cons
You are 100% commission, so if you have a tough month you will work long hours to make more $$. Your managers will pressure you to work on off days or stay late to make your personal shortfall. (Don't take it personal, their compensation is based on your performance and they want a bonus too!) You will LIVE at the club in sales roles. Your social life becomes your colleagues and members. You will work weekends - no way around it
