I like that you get a full body workout in one hour. I like the coaches (Juan and Kenny, especially) who keep you focused and engaged for the entire hour. I recently tried a workout in DC while in a business trip. The coaches there paled in comparison to our guys.
I love everything about OrangeTheory! Everything from the instructors, the diversity in the workouts, the upbeat music, and the fun contests that increase morale while we are all giving each workout our all... I love it all!
I LOVED my sample workout at OrangeTheory recently. Currently, I have a full workout schedule, but am making room starting June 1st to include OrangeTheory as a regular weekly routine to replace my twice a week trainer. This is so much more reasonable and just as effective!
OTF is a complete workout - the cardio is excellent, the floor work changes all the time and the pace makes the hour go past really quickly. It's like having a personal trainer but the group makes it more of a challenge and spurs you on. It's awesome!
