I love that it's an all-around workout with both strength and cardio crammed into an hour-long class! I've been sticking with OTF workouts regularly for 9 months and I feel great. I am probably stronger now than I've ever been in my life.
Everything! The trainers the music the energy the workout itself. People around me are probably tired of hearing about orange theory. As much as I tell everyone how awesome it is they probably think I'm getting paid. Lol! Also love the heart rate monitoring.
