There are three things that I love about OT and which I believe is unique to other group workouts:
Every class is different - not just different exercises but different structure and intensities.
Every class combines cardio and strength.
Every class is taught by trainers who personally oversee your workout.
I'm a fan!
Love Orangetheory. Love that the workout is different everytime I go. It never gets old. Also the staff and instructors are very helpful and friendly. I really look forward to going to my workouts at Orangetheory.
