I went to spin class last night, and the chart above is my evidence! I remembered to wear my heart rate monitor to class and recorded the whole class. I'm also very excited that I figured out how to get the chart in here.
If you look towards the middle of the class,you can see the time where I was actually feeling dizzy and ill.....I looked down at my watch to check my watch to check my heart rate: 187. A tad high. Okay, okay, before you freak out, let me assure that I wasn't feeling super dizzy, only a little...and it was a though part of the class. Cadence on a very steep simulated climb.
I'm feeling great this morning, although a bit tired. I went to bed late for a school night. Thank God Thursday is usually a day of rest for me. I am tempted to try to get a 20 minute run in between job number 1 and job number 2...but that really depends on how long the student discussion meeting lasts at job1.
