I love the challenge each workout provides! I also like the fact that it's always different. The coaches are always very helpful if you are having a hard time with a particular set during strength training.
It pushes me harder than I would normally push myself on my own at the gym. The trainers and staff is incredibly nice and encourage you to do your best! They pump you up and get you excited about working out.
I like the high energy of the trainers. It's very evident they believe in the Orange Theory and they do an awesome job transferring that energy to the class. I like that I can have a routine time slot or go at a random time and I'm still getting a variety workout. I'm never bored and it never feels repetitious.
