I love all the trainers here - it's an excellent group circuit workout and Nikki remembers every single persons name somehow. It's amazing how fast an hour goes when you are working so hard, but it's fast-paced, different exercises each class, and the instructors are very encouraging. I work out often and I am definitely not new to challenging workouts, but this is a great place to push yourself. The classes can be crowded so it's a good idea to register in advance.
