I do hill walking intervals on the treadmill, also. I really can't run, either, even though I want to.
Went to spin this morning, even though it's a rest day, usually. I didn't get up early yesterday, so it made it easier to get up today! The class was OK, I just look at the instructor in amazement when she is pedaling with a super high cadence (at least 110+) and telling us to increase the resistance. I just can't believe her resistnce is up that high... but, at least there's one other person in the morning who comes in bike clothes
. The rest are tri-athletes, or just the same people who do boot camp on the other days. I do notice a lot about group behavior, patterns with these classes. The group of tri people tend to follow some of the instructors like groupies and tend to take tons of classes, do training at several different gyms. They usually are runners first, some swimmers first, but never cyclists. They are definitely faster riders than me (they once asked me to come on a ride and when she told me the average, I laughed and declined), but seem to think the cycling I do is "amazing." Not really. Some of them remind me of the people in the Athleta catalog!
