My only regret in going to Susan's class is that I didn't find her sooner! Susan is a fantastic spin instructor. Admittedly, the best I've ever had! She has contagious energy and her participation herself keeps you on pace throughout the class. Her playlists do NOT disappoint. In fact, I've started following her on Spotify, so I can continue to listen to her music for my other workouts. I always get an intense workout in with Susan, but she engages the crowd with mixing up her rides between hills/jumps/sprints, so I rarely find myself looking at the clock. She will be VERY missed by us Boston riders. I LOVE her workouts and most importantly, she's in fabulous shape herself and always manages to kick our butts in the workouts. A great role model!
