When I take a spin class I have a tendency to not work all that hard. I zone out and my heart rate barely gets above 140. Often I really need to push it to get it above 145. I need strong, steady work to really tax my cardio system, so my poor peeps have to live in my world! It is super fun for me to be watching my own watts and then looking out to see how the class is doing (everyone has a computer on their bike and based on their FTW test they dial in their watts). Yellow is up to 105% of FTW - slightly different calculation from FTP. Red is 105% and above.
The gang was awesome today and I would have to think that most had a HR chart fairly similar to mine. Would be great to have the watts mapped on here as well 'cause we were pushing it. The last build was on a hill trying to chase the watts - to Adele's Skyfall. I spent more time over 200 watts today than probably - ever. Average HR was 139 and max was 167. I was still talking and teaching, so have some room there! We'll be doing this class again :-)
