I'm a pretty big Spynga fan! I first tried it with a friend who wanted company (at Spynga south), and loved it right away. You can work at your own pace, the instructors are friendly (and helpful), and the group is really fun. I'm now a regular at Spynga north - it's so close to me, that I have no excuse not to work out! The front desk folks are amazing - they always remember me by name, even when I've taken a few weeks off :) For your first class, come early, bring some water, and be prepared for a great workout!
