I started OTF in Pleasanton, CA in 2015 and it is the best gym and workout I have ever experienced. I moved to OTF in Berkeley but mostly went to the Alameda OTF which is now my favorite studio. Then I moved to LA and did OTF on Sunset Blvd. That was a great gym too. Then, alas, I moved two hours north of the closest city (SF/OAKLAND) and I can only go every once in a while. I actually would love to own and open an OTF where I live but when I looked into it, they said that the town is too small.
OTF is an all encompassing workout for any level of fitness. It teaches you about heartrate zones and how to workout no matter what you are working on.
I love it and can't wait to go on Sunday.
