ClassPass

I’m just finishing up my first month with class pass and I LOVE it. You have access to studios all throughout the bay area, so you can take classes wherever you happen to be on any given day. I usually take classes near work in San Francisco or home in Oakland, but I’ll also drive 20 or 30 minutes if I see a class that looks interesting elsewhere.
The restrictions are three classes per month at each studio, you can only have four reservations outstanding at any given point in time, and there’s a $ 15 fee for cancelling classes on less than 12 hours notice. On the studio’s end, they open a limited number of spots for classpass attendees but it’s rare for me to come across a class that’s full when I’m browsing. That is the nice thing about the restrictions and cancellation policy – it doesn’t allow people to take spots in classes and then blow them off. As long as you’re not in love with one particular studio, there’s no shortage of the basics (barre, yoga, bootcamp, boxing, dance).
The $ 120 price tag is a little steep, but worth it. And they have a great referral program so if anyone would like $ 20 off your first month, sign up through this link :)

ClassPass membership started out awesome but is something you have to regularly evaluate.
I joined in March 2015 when it was $ 99 for unlimited classes and all of the studios I had tried through various Groupons and LivingSocial deals were in the network. It was a no-​brainer. A year into it now, I have seen my favorite reformer Pilates studio reduce available classes and then drop out entirely (Mighty Pilates), my other favorite heated yoga studio reduce classes to just 1 or 2 a day (CorePower), and the fee has gone up $ 20. If you’d rather not pay $ 120/​month for unlimited, they offer you 8 classes for $ 100, which seemed reasonable to me since I was logging about those many classes anyhow. If Yogaworks drops out, I will be dropping ClassPass.
