I started going to Orangetheory last month. I had been bouncing from gym to gym and couldn't find anything that worked for me. That all changed a few weeks ago.
I'm officially addicted. Each workout at Orangetheory is different, and the fact we wear heart rate monitors allows the trainers to modify the classes to adjust to the group and our individual needs.
The workouts are hard but fun, and it's gotten my fitness routine back on track. I went four times last week. I'm also obsessed with getting my performance results. You earn a "Splat Point" for every minute spent in the orange/red heart rate zone, and now I'm obsessed with earning as many as I can.
To sum it up, if you're looking for a fun HIIT style workout, like picking through your performance data, are intrigued at the thought of a Splat Point, or just want a workout towel that says "Keep Burnin" - Check out OTF.
