Orange theory fitness [View all]

I used to play racquetball when I was younger and did a lot of cardio and strength training to help me be better. It worked. But my knees wore out as I got older. I can still do the cardio, but the quick starts / stops and pivots on the knees make racquetball a thing of the past.

Now I am going to "orange theory" which is high intensity interval training, group training class. Very intense and over in an hour. But makes you feel great afterwards. Think of it as P90x for sane people. LOL!

Anybody else here tried OTF?
