New Toys

Jen got me a GPS watch for Christmas. It comes with a heart rate monitor and loads of other neat stuff. It's been fun to take it out on the trails and then come back and upload the data. I've never had that kind of visibility into my workouts before.

Today I decided to use it for a crossfit workout. The workout is called Barbara, which consists of the following:

5 rounds for time:
20 pullups
30 pushups
40 situps
50 squats
3 minutes rest

Below is a plot of my heart rate over the duration of the workout. I started the clock right when I started and stopped it right when I was finished, so the plot starts and stops at those instants. The workout took me 41 minutes and 31 seconds.


My heart rate for Barbara

You can clearly see the four rest periods. The sharpest peaks are at the end of the pullups; I can bang out twenty of those nonstop using the butterfly method (a way to recycle more of your energy from one pullup to the next, generally accepted in crossfit workouts). The other peaks are during the squats, as I can string together long sets of those as well. The lulls are during the pushups and situps. I have to stop several times per round for those exercises.
