Best hour workout EVER!!! I've been Going to OTF once or twice a week in addition to my other workouts for the past three months and I LOVE IT!!!! I always leave feeling like I accomplished an excellent workout! Although I've gone to classes with various instructors, Emily is my favorite instructor! She is sweet as can be until class starts, then she will push you to the brink!!!! If you haven't tried OTF, you are missing out!!!! OTF will challenge you and improve your fitness no matter what your goals are.
