I thought I'd report back on what we decided. As a recap, we are longtime members at Urban Active/Golds but they cancelled the group fitness classes at our location last month. They had a class which was the sole reason I renewed in May. We got a 7-day pass a few weeks ago to Lifetime and I tried all kinds of classes that week. It went so well that we joined!
The main reason we joined was because of the barbell class (strength training) like the one I took at Urban Active but I love some of the other classes I've tried. The latin fusion dance class is my new love but hip hop was also fun. The pool/jacuzzi and locker room facilities are wicked cool, too.
We got a monthly couples membership and added my stepson on for a reasonable fee. There is a ton for all of us to do there and it's no further to drive than our Urban Active location.
Thanks to everyone who provided feedback on my original post!
