To join or not to join....

I'm debating on whether or not I'll join a new gym in the neighborhood. I had a membership years ago (pre-graduate school) to which I got really good use out of. Once I started school (and relocated), it just wasn't a priority. Even if I joined, I would not have had time to really use it. In between studying, working and just enjoying my free time, the gym was the last thing on my mind. However, I managed to maintain my yoga on wednesdays and aerobics on weekends. I actually considered myself pretty 'fit' for just half-way trying. But now, it's time to get back in the saddle. I need to find a place that offers classes. Think it's time to start learning how to zumba...
