Jazzercise

Does anyone here do Jazzercise? I go there 4 nights a week for an hour each night, and I wonder how many calories and fat I am buring. I am also wondering if I should bump up to adding another class to make the exercise 5 nights a week. I started going to these classes back in January(started walking as an exercise back in November of 2009) I am seeing some results already, I guess I just am getting impatient with myself.

Being patient is one great help when having an exercise or when you wish to lose some weights. Of course losing weight wouldn't be that easy to anyone else and I'm proud of what you have done.

Thank you!!!!
