Alissa is a fantastic instructor. She is very knowledgeable and understands how the body works and in particular the subtleties of an exercise in relation to the body. She explains and demonstrates everything clearly. She never misses a beat observing my workouts and has a keen eye making sure I am doing things correctly or if I'm uncomfortable with a move. By the time the session has ended I feel energized and less tired than when I began. Her classes are fun and engaging. It's a great vibe. I highly recommend her classes.
