Just as the title asks.  I'm thinking about starting, there's a place here in town, $90 a month for coach led classes every day.  I have no idea what to do to even get started in a gym, or even on my own, so I NEED some leadership and encouragement.  I know they also change the workout every day.
 
	What can I expect?  
 
	Any reason why I should NOT do it? What would be better?
 
	Discuss.
