I went to a class Monday (6 am) and wasn't crazy about the instruction. She used perceived effort, I prefer cadence. She wasn't overly energetic which might have been okay if it weren't intended to be my morning pick me up! Plus her workout didn't seem to closely mirror the music like the guy I had been attending classes with. I did try a different instructor (my third) last night and I really clicked with her. Still like the Thursday night guy the best. Been to three of his classes and I can see why they are always full. But I am definitely enjoying spin and finding workouts to challenge me. I have one of my teammates who comes on Thursdays. It is nice to have a buddy!
