If you are a member of the pro-club and fantasize about how great your bod would be if you had a personal trainer - but are too frugal to fork over the cash, may I recommend the Circuit Training class? It's one of the punch card classes (25 dollars buys you 10 classes), and you basically do a mix of strength training and cardio.
The good thing is that you can adjust the weights you use and the cardio machines to your level. The bad thing is that no adjustment can be made to doing reps and reps of lunges. But that's what you're there for, right? Right? It is intense - but in a good way.
The first class, you will leave wiped out. And, well, every class really. But I also leave feeling like I got a total and complete workout.
