The introduction class is a joke. Free if you think buying $19 socks are free. (As the picture indicate the receipt made it even worse because of the ($6.00) in parenthesis. Either they jack up the rate they charge for "free" class or they have a 200% markup on socks ?) By the way the class was so simple the socks weren't needed. It was 30-40min tops of work (I truly didn't even break a sweat) then 10min hardcore sales pitch where, I kid you not, they keep your ID until you are asked: "which membership would you like to sign up for today?" It's not hard for me to say neither but the older ladies in class seemed overwhelmed and I felt heartbroken for this horrifically hard core sales tactic. A used car salesman would blush. Don't let anyone keep your ID ever!
