Hi there, thanks -- I decided to log my way through the last two month's before O-Ringen. :-)
Orange Theory is a nationally franchised workout studio -- they offer classes of about one hour of high-intensity interval training. I did it as a guest with a friend back in April and caught the bug. I like it because a) I don't have to plan : I show up and the coach tell me what to do. Every class has a different "template" of weights and cardio. And b) I work out much harder than I would on my own.
The "orange" comes from their approach to effort; they divide heart rates into 5 zones, with the goal to spend as much of the class as possible in zones green, orange or red: 71%, 84% and 94% of max heart rate, respectively. They gamify it so that every minute you spend in zone 4 -- the orange zone -- you earn a "splat point" (which is supposed to mean a fat cell exploding). Staying at least 12 minutes in that zone is the goal per class.
It's a bit arbitrary. They don't use the standard max heart rate calculation of 220 - age. They bump it up to 225 for men and 230 (!) for women. This makes it almost impossible for me to get into orange, and I've never been in the red zone . Other people are in the orange zone from the minute they walk into the studio. That annoys me a bit, but they remind us that "everyone's heart rate is different."
Looks like they don't have one in Lawrence, but there are several in KC. (www.orangetheoryfitness.com
